Container registries are the storage backbone of modern deployment — every container that runs in production was pulled from one. MCP servers for registries let AI agents search for images, manage repository metadata, push builds, and scan for vulnerabilities without the developer juggling CLI tools and web consoles.

The headline finding: official vendor investment is strong and expanding. Docker Hub has an official 13-tool MCP server. JFrog now offers both an experimental open-source server and an official remote hosted MCP server, plus a Universal MCP Registry for governing MCP servers as artifacts. AWS provides ECR access through ECS and Finch MCP servers (now with a hosted option). Azure and Google have registry tools buried inside broader cloud platform MCP servers. And the biggest gap is finally closing: Stacklok’s OCI Registry MCP server provides the first universal container registry client that works with any OCI-compliant registry.

Category: Developer Tools

The Landscape

Docker Hub (Official)

Server	Stars	Language	Tools	Auth	Transport
docker/hub-mcp	~140	TypeScript	13	Optional PAT	stdio

Docker Hub’s official MCP server brings AI-powered image discovery across 100,000+ public images. 140 stars (+8%), Apache 2.0, backed by Docker, Inc. Requires Node.js 22+. Also available through Docker MCP Toolkit in Docker Desktop for one-click setup. Docker Desktop 4.67.0 (March 30, 2026) added MCP profile template cards with an onboarding tour and fixed CVE-2026-33990 (SSRF vulnerability in Docker Model Runner’s OCI registry client).

13 tools across three domains:

Image Discovery (2 tools):

Tool	What it does
`search`	AI-powered search across Docker Hub with architecture and OS filtering
`docker_hardened_images`	Discover Docker’s security-hardened official images

Repository Management (5 tools):

Tool	What it does
`get_namespaces`	List available Docker Hub namespaces
`list_repositories_by_namespace`	Browse repositories within a namespace
`get_repository_info`	Full repository metadata — description, stars, pulls
`check_repository`	Verify a repository exists
`create_repository`	Create a new repository (requires PAT)

Tag Management (4 tools):

Tool	What it does
`list_repository_tags`	Browse available tags with filtering
`read_repository_tag`	Inspect a specific tag — layers, size, architecture
`check_repository_tag`	Verify a tag exists
`update_repository_info`	Update repository description and settings

The AI-powered search is the standout feature — it understands natural language queries like “lightweight Python image for machine learning” and filters by architecture (ARM64, AMD64) and OS. Without authentication, you get read access to public images. With a Personal Access Token, you unlock repository creation and private repo access.

The Docker MCP Toolkit integration means Claude Desktop, Cursor, and VS Code users can enable this with a single click — no manual JSON configuration. That’s the lowest setup friction of any server in this review.

Also notable: QuantGeekDev/docker-mcp — 428 stars, Python, MIT, 4 tools for Docker engine management (create-container, deploy-compose, get-logs, list-containers). This manages running containers, not the registry itself. See our Docker MCP Server review for container runtime management, and ckreiling/mcp-server-docker (702 stars, 19 tools) for the most comprehensive Docker engine MCP server.

JFrog Artifactory (Official)

Server	Stars	Language	Tools	Auth	Transport
jfrog/mcp-jfrog	~115	TypeScript	22+	JFrog token	stdio, SSE
jfrog/jfrog-mcp-server	~7	TypeScript	4 categories	OAuth	Remote hosted

JFrog now offers two MCP server options. The experimental mcp-jfrog (115 stars, 17 commits) remains available for local use, but JFrog now explicitly directs users to the official remote hosted MCP server (jfrog-mcp-server, 7 stars, 31 commits) — a cloud-hosted server maintained by JFrog with OAuth authentication and automatic tool updates. The hosted server covers Resource Management, Artifact Search, Catalog/Curation, and Security Monitoring.

Also new: JFrog Universal MCP Registry (launched March 18, 2026) — treats every MCP server as a governed artifact with centralized discovery, configuration, and project-level permissions. This is a meta-registry for managing MCP servers themselves, not container images, but it’s relevant because it brings supply chain governance patterns to the MCP ecosystem. Available as part of JFrog AI Catalog.

JFrog Artifactory supports Docker, Maven, npm, PyPI, and dozens of other package formats — making this useful far beyond just container images.

22+ tools across six categories:

Repository Management (7 tools): check_jfrog_availability, create_local_repository, create_remote_repository, create_virtual_repository, list_repositories, set_folder_property, execute_aql_query. The AQL (Artifactory Query Language) tool is powerful — it lets agents write structured queries to find artifacts across all repositories.

Build Management (2 tools): list_jfrog_builds, get_specific_build. Track which builds produced which container images — critical for traceability.

Runtime Monitoring (3 tools): list_jfrog_runtime_clusters, get_jfrog_runtime_specific_cluster, list_jfrog_running_images. See which container images are actively running across your infrastructure. This is a unique capability — no other MCP server in this review connects registry data to runtime state.

Access Control (4 tools): list_jfrog_environments, list_jfrog_projects, get_specific_project, create_project. Project and environment management for multi-team setups.

Catalog & Curation (5 tools): jfrog_get_package_info, jfrog_get_package_versions, jfrog_get_package_version_vulnerabilities, jfrog_get_vulnerability_info, jfrog_get_package_curation_status. The vulnerability tools integrate with JFrog Xray — agents can check CVEs for any package version before using it.

Security Scanning (1 tool): jfrog_get_artifacts_summary. Combined vulnerability and compliance summary for artifacts.

The runtime monitoring + vulnerability scanning + artifact management combination makes this the most complete “artifact lifecycle” MCP server. If your organization uses JFrog, this server covers the full pipeline from build to deploy to runtime observation.

AWS ECR (via ECS + Finch MCP Servers)

AWS doesn’t have a dedicated ECR MCP server. Instead, ECR functionality is distributed across two servers in the awslabs/mcp monorepo (~8,900 stars, up from ~4,700, Apache 2.0, 1,487 commits):

ECS MCP Server

Server	Stars	Language	Tools	Auth	Transport
awslabs/mcp — ecs-mcp-server	~8,900*	Python	7+	AWS credentials	stdio, hosted

The ECS MCP server includes ECR repository creation and image push as part of ECS deployment workflows. Python 3.10+. Available via pip (awslabs.ecs-mcp-server) or as an AWS-managed hosted MCP server — the hosted option is now recommended, with the legacy local installation no longer receiving updates.

ECR-relevant tools: containerize_app (generate Dockerfiles), build_and_push_image_to_ecr (automated ECR repo creation via CloudFormation + Docker build + push), ecs_resource_management (manage ECS resources including ECR image references). The server handles IAM roles with push/pull permissions, returns full image URIs, and integrates with load balancers and auto-scaling.

The ECR integration is tightly coupled to ECS deployment — you can’t use it for standalone registry management without the ECS context. Good for deployment pipelines, not for browsing or managing ECR repositories independently.

Finch MCP Server

Server	Stars	Language	Tools	Auth	Transport
awslabs/mcp — finch-mcp-server	~8,900*	Python	3	AWS credentials	stdio

Finch (AWS’s open-source container tool) gets a dedicated MCP server for building and pushing images. 3 focused tools:

Tool	What it does
`finch_build_container_image`	Build images with multi-platform support
`finch_push_image`	Push to ECR with hash-based tagging and credential verification
`finch_create_ecr_repo`	Create ECR repositories with immutable tags via boto3

The immutable tags enforcement is a security best practice — preventing tag overwriting that could introduce supply chain attacks. The finch_push_image tool verifies ECR credential helper configuration before attempting pushes, which prevents the common “no basic auth credentials” error.

Star count shared across all servers in the awslabs/mcp monorepo.

Azure ACR (via Microsoft MCP)

Server	Stars	Language	Tools	Auth	Transport
microsoft/mcp	~3,000	C#	2 ACR tools	Azure credentials	stdio, .mcpb

Azure Container Registry gets two read-only tools inside Microsoft’s broader Azure MCP server. 3,000 stars (up from 2,800), MIT, now covers 45+ Azure services with 230+ tools total. The Azure MCP Server is now also available as an MCP Bundle (.mcpb) (April 22, 2026) — install into Claude Desktop and other MCP-compatible clients with no runtime required. Azure MCP tools are also built into Visual Studio 2022 and 2026 natively.

ACR-specific tools:

Tool	What it does
`azmcp-acr-registry-list`	List ACR registries in a subscription, optionally filtered by resource group
`azmcp-acr-registry-repository-list`	List repositories within an ACR registry

Still two tools, both read-only. No image pushing, no tag management, no vulnerability scanning. This is enough for discovery (“What registries and images do we have?") but not for any registry management workflow. The .mcpb bundle format does lower setup friction significantly.

Available via NuGet, npm, Docker, or .mcpb bundle. All tools are designed to be non-destructive and idempotent — consistent with the overall Microsoft MCP server philosophy.

Harbor (Community)

Server	Stars	Language	Tools	Auth	Transport
nomagicln/mcp-harbor	~6	TypeScript	11	Harbor credentials	stdio

The only MCP server for Harbor, the CNCF-graduated open source container registry. 6 stars, MIT, Node.js 18+. Small community project but functionally complete for basic Harbor management.

11 tools across four domains:

Project Management: list_projects, get_project, create_project, delete_project

Repository Management: list_repositories, delete_repository

Tag Management: list_tags, delete_tag

Helm Charts: list_charts, list_chart_versions, delete_chart

This covers the core Harbor workflow — create projects, manage repositories and tags, handle Helm charts. The Helm chart management is a nice addition that reflects Harbor’s role as a multi-artifact registry (not just container images). Missing: vulnerability scanning integration (Harbor has built-in Trivy scanning that isn’t exposed here), robot account management, replication policies, and garbage collection triggers.

Setup requires manual clone + npm install + build — no one-click install option.

Sonatype Nexus (Community)

Two community MCP servers cover Nexus Repository Manager:

brianveltman/sonatype-mcp

Server	Stars	Language	Tools	Auth	Transport
brianveltman/sonatype-mcp	~7	TypeScript	16	Nexus credentials	stdio

The most comprehensive Nexus MCP server with 16 tools spanning repository, component, asset, system, and firewall management. 7 stars, Node.js 18+. Installable globally via npm.

Repository tools (5): list, get, create, update, delete. Component tools (5): search, get, delete, get versions, upload. Plus system tools (status, blob stores, tasks, metrics, support zip) and optional firewall quarantine management. The firewall tools for quarantine retrieval and release are useful for organizations using Nexus Firewall to block suspicious components.

Covers Docker-hosted repositories alongside Maven, npm, PyPI, and other formats.

addozhang/nexus-mcp-server

Server	Stars	Language	Tools	Auth	Transport
addozhang/nexus-mcp-server	~1	Python	6	Header auth	HTTP streaming

A lighter alternative focused on read-only queries, with explicit Docker support. 1 star, MIT, February 2026. 6 tools: search_maven_artifact, get_maven_versions, search_python_package, get_python_versions, list_docker_images, get_docker_tags.

The list_docker_images and get_docker_tags tools are Docker-specific — browsing container images stored in Nexus Docker repositories. Supports SSE and streamable HTTP transport. Available as a Docker image (addozhang/nexus-mcp-server).

GCP Artifact Registry (Community)

Server	Stars	Language	Tools	Auth	Transport
enesbol/gcp-mcp	~6	Python	Multiple	GCP credentials	stdio

The only MCP server covering Google Cloud Artifact Registry, buried inside a broader GCP services MCP server. 6 stars, MIT, single-developer project. Covers 8 GCP services: Artifact Registry, BigQuery, Cloud Build, Compute Engine, Cloud Run, Cloud Storage, IAM, and Pub/Sub.

Artifact Registry tools handle container and package management — listing repositories, browsing images, managing versions. But this is a community project with minimal adoption. Google has no official Artifact Registry MCP server, which is a notable gap given that GCP is a major cloud platform and Google has been investing heavily in MCP across other products.

Available via pip or Docker. Includes AI-guided configuration helpers.

Container Image Scanning (via Trivy)

Server	Stars	Language	Tools	Auth	Transport
aquasecurity/trivy-mcp	~37	Go	Multiple	Optional	stdio, HTTP, SSE

Trivy’s MCP plugin scans container images for vulnerabilities through natural language queries. 37 stars, MIT, official Aqua Security project, 67 commits, v0.0.20 (December 2025). Installs as a Trivy plugin (trivy plugin install mcp, then trivy mcp). Supports VS Code, Cursor, JetBrains IDEs, and Claude Desktop. Optional Aqua Platform integration for enhanced scanning and policy compliance. Note: Trivy experienced a security incident in March 2026 (malicious v0.69.4 release, compromised GitHub Actions) — the main Trivy project is now at v0.70.0 with incident resolved.

While covered in our Code Security MCP Servers review, Trivy is relevant here because container image scanning is a core registry workflow. Ask “Are there any critical CVEs in nginx:1.25?” and Trivy scans the image layers. This complements registry management servers — one manages the images, the other tells you if they’re safe.

Trivy is the most widely-used open source container security scanner (23k+ stars on the main repo), so having an MCP plugin matters for registry workflows that include security gates.

OCI Registry (Universal — NEW)

Server	Stars	Language	Tools	Auth	Transport
StacklokLabs/ocireg-mcp	~12	Go	4	Multiple	SSE

The first universal container registry MCP server — works with any OCI-compliant registry. 12 stars, Apache 2.0, 126 commits, v0.3.0 (March 26, 2026). This fills what was previously the biggest gap in this category.

4 tools:

Tool	What it does
`get_image_info`	Retrieve image details: digest, size, architecture, OS, creation date, layer count
`list_tags`	Enumerate available tags for a repository
`get_image_manifest`	Fetch the OCI manifest for a container image
`get_image_config`	Obtain configuration data for a container image

Supports multiple authentication methods: HTTP bearer tokens, environment variables, and Docker config file (~/.docker/config.json). Tested with Docker Hub and GitHub Container Registry (GHCR). Since it speaks the OCI Distribution API, it should work with any compliant registry — ECR, ACR, GCR, Harbor, Quay, and private registries.

Recommended deployment via ToolHive for container isolation, encrypted secret management, and network policies. This is a read-only tool — no image pushing or tag management, but it covers the most common “what images do we have and are they safe?” workflow across any registry.

This is a significant development — rather than building vendor-specific servers for each registry, one universal client that speaks OCI covers the common ground. Vendor-specific servers (Docker Hub, JFrog, etc.) still provide richer features like AI-powered search, vulnerability scanning, and lifecycle management.

GHCR and Other Registries

GitHub Container Registry (GHCR): No dedicated MCP server. GitHub’s official github-mcp-server covers GitHub APIs broadly but doesn’t expose GHCR-specific tools. The community rideRTD/RTD-DevOps helper includes ghcr_login_guide and ghcr_push tools, but it’s a small DevOps utility, not a GHCR management server.

Quay.io: No MCP server found. Red Hat’s container registry lacks MCP integration.

GitLab Container Registry: No MCP server found. GitLab’s broader MCP efforts don’t yet cover their registry.

DigitalOcean Container Registry: No MCP server found.

What’s Missing

The container registry MCP ecosystem has narrowed its gaps since March, but several remain:

Universal registry client exists but is read-only — Stacklok’s OCI Registry MCP server (ocireg-mcp) fills the biggest previous gap by working with any OCI-compliant registry. But it only supports read operations (4 tools). No universal client yet handles image pushing, tag management, or lifecycle operations.
Image lifecycle management — no server helps with tag retention policies, garbage collection, or automated cleanup of old images. This is one of the most common registry maintenance tasks.
Multi-registry synchronization — no server helps mirror or replicate images across registries. Organizations running hybrid cloud need this.
SBOM and provenance — with supply chain security becoming critical (see Trivy’s March 2026 incident), no registry MCP server exposes SBOM data or image provenance (Sigstore/cosign signatures). JFrog’s Xray integration is the closest.
GHCR still uncovered — Stacklok’s OCI server works with GHCR for read operations, but there’s no dedicated GHCR management server. GitHub’s official MCP server still doesn’t expose GHCR-specific tools.

The Bottom Line

Rating: 3.5 / 5 — The arrival of Stacklok’s universal OCI registry server closes the biggest previous gap, and JFrog’s shift to a hosted MCP server plus Universal MCP Registry signals enterprise maturation. AWS’s monorepo nearly doubled in stars (4,700→8,900) and now offers hosted MCP server options. But Azure and GCP coverage remains minimal (2 read-only ACR tools, 6-star community GCP project), Harbor and Nexus community servers are dormant, and advanced workflows — lifecycle management, cross-registry sync, supply chain verification — still require manual tooling.

Best for image discovery: Docker Hub MCP (docker/hub-mcp) — AI-powered search across 100k+ images, one-click Docker Desktop setup.

Best for artifact lifecycle: JFrog MCP — the official hosted server (jfrog-mcp-server) for production, or the experimental mcp-jfrog (115 stars) for local development. 22+ tools covering repositories, builds, runtime monitoring, and vulnerability scanning.

Best for AWS workflows: ECS + Finch MCP servers — tight ECR integration with secure defaults (immutable tags, IAM role management). Hosted MCP server option now recommended.

Best for cross-registry queries: Stacklok OCI Registry MCP (ocireg-mcp) — 4 read-only tools that work with any OCI-compliant registry. The universal client this category needed.

Best for self-hosted registries: Harbor MCP (nomagicln/mcp-harbor) — 11 tools for projects, repositories, tags, and Helm charts. Or Sonatype MCP (brianveltman/sonatype-mcp) for Nexus.

The container registry MCP space continues maturing. The shift toward hosted/remote MCP servers (JFrog, AWS) and universal protocols (Stacklok’s OCI client) points toward a more connected future, but advanced registry workflows still require manual tooling. The Trivy supply chain incident in March 2026 underscores why registry security tooling matters.

Browser Extension MCP Servers — Chrome DevTools, Browser Automation, Firefox, Safari, WebMCP, and More

Browser extension MCP servers for AI-powered browser control, DevTools debugging, automation, and web inspection across Chrome, Firefox, Safari, and emerging browser-native standards. **The official Chrome DevTools MCP** — ChromeDevTools/chrome-devtools-mcp (37,700 stars, TypeScript) is the clear leader, now with 34 tools across 8 categories including input automation (9), navigation (6), emulation (2), performance (3), network (2), debugging (6), extensions (5), and memory (1). Experimental vision with coordinate-based tools, WebMCP debugging support for Chrome 149+, and screencast recording. Official Google project with rapid development (805 commits). **Chrome extension pioneer** — hangwin/mcp-chrome (11,400 stars, TypeScript) takes a fundamentally different approach: instead of launching a new browser, it uses your existing Chrome browser as a Chrome extension. This means AI agents inherit your login sessions, cookies, bookmarks, and browser configuration. 20+ tools including tab management, content extraction, semantic search, DOM interaction, network monitoring, and screenshots. The extension architecture avoids bot detection since it operates within a real user browser session. **Browser monitoring suite DISCONTINUED** — AgentDeskAI/browser-tools-mcp (7,200 stars, TypeScript) has been officially discontinued. The README now states 'THIS PROJECT IS NO LONGER ACTIVE PLEASE USE A DIFFERENT SOLUTION.' Additionally, an OS command injection vulnerability (CWE-78) was reported in April 2026 affecting macOS deployments with autoPaste enabled. Users should migrate to alternatives like chrome-devtools-mcp or mcp-chrome. **Local-first automation** — BrowserMCP/mcp (6,400 stars, TypeScript, Apache-2.0) is a Chrome extension + MCP server adapted from Playwright MCP to automate your actual browser rather than creating new instances. Fast local automation without network latency, keeps activity private on-device, maintains logged-in sessions, and avoids basic bot detection by using your real browser fingerprint. Works with VS Code, Claude, Cursor, and Windsurf. **Browser-native standard advancing** — WebMCP (1,100 stars, TypeScript, AGPL-3.0) has been accepted as a W3C deliverable and is transitioning to official web standard development via the webmachinelearning/webmcp repository. Websites register tools via navigator.modelContext API. Now available in Chrome 146+ Canary and Microsoft Edge 147 (added March 2026). Chrome DevTools MCP integrates WebMCP debugging support for Chrome 149+. The WebMCP-org GitHub organization hosts core packages, examples, and documentation. MCP-B extension is no longer open source. **Safari gap FILLED** — achiya-automation/safari-mcp NEW (47 stars, JavaScript, MIT, 80 tools) provides native Safari browser automation via AppleScript + Swift daemon. 80 tools across 19 categories including navigation, page reading, clicking, form input, screenshots/PDF, scrolling, tabs, JavaScript execution, element inspection, accessibility, drag-and-drop, cookies/storage (10 tools), clipboard, networking (6 tools), and console. ~60% less CPU than Chrome on Apple Silicon, ~5ms latency per command, zero-overhead background operation preserving logins. Framework-aware (React, Vue, Angular, Svelte). The biggest gap from the initial review has been filled. **Safari alternative** — lxman/safari-mcp-server (32 stars, TypeScript, MIT, 9 tools) provides Safari automation via SafariDriver with session management, DevTools access (console, network, performance), screenshots, and JavaScript execution. Less comprehensive than safari-mcp but more DevTools-focused. **Official Mozilla Firefox DevTools** — mozilla/firefox-devtools-mcp (131 stars, TypeScript, MIT, v0.9.2) — the freema/firefox-devtools-mcp project has been adopted by Mozilla and moved to the official mozilla/ GitHub organization. 189 commits. Features page management, snapshot/UID interactions, input handling, network capture, console monitoring, screenshots, script evaluation, privileged context access, WebExtension management, and Firefox preferences control. Claude Code plugin available. Install via npx firefox-devtools-mcp@latest. **Security-focused Firefox control** — eyalzh/browser-control-mcp (277 stars, TypeScript, v1.5.1) pairs an MCP server with a Firefox extension that prioritizes safety: local-only connection with shared secret, extension-side audit log for tool calls, tool enable/disable configuration, domain-level consent for content reading, and zero third-party runtime dependencies. Tab management, history access, named tab groups with colors. Available on Firefox Add-ons. **Firefox multi-session automation** — JediLuke/firefox-mcp-server (TypeScript) provides 28 specialized tools for Firefox automation via Playwright. Isolated browser sessions with independent cookies/storage, concurrent multi-session management, real-time console monitoring, WebSocket traffic capture, network activity monitoring with timing data, and performance metrics (DOM timing, paint events, memory usage). Experimental/vibe-coded project. **Lightweight Chrome CDP control** — lxe/chrome-mcp (47 stars, TypeScript) provides granular Chrome control via Chrome DevTools Protocol without screenshots. Navigate, click coordinates/elements, type text, get semantic page info including interactive elements and text nodes, and query page state (URL, title, scroll position, viewport). SSE transport. Requires Chrome with remote debugging enabled. **Community Chrome DevTools** — benjaminr/chrome-devtools-mcp (296 stars, TypeScript, v1.0.3) provides Chrome DevTools Protocol integration for Claude Desktop and Claude Code. Element inspection, console access, and browser automation. Predates the official ChromeDevTools version. **Cross-browser extension** — djyde/browser-mcp (12 stars, TypeScript) supports Chrome, Edge, and Firefox with a unified extension. Get markdown from the current page, summarize page content, inject CSS (e.g., dark mode), and search browser history. Lightweight multi-browser approach. **WebSocket page bridge** — Oanakiaja/chrome-extension-bridge-mcp (TypeScript) establishes a WebSocket connection between web pages and a local MCP server, exposing the global window object. Useful for interacting with web application state from AI tools. **Comprehensive browser bridge** — robhicks/browser-mcp-bridge (TypeScript) provides full browser content bridging to Claude Code: page content extraction, DOM snapshots with computed styles, JavaScript execution in page context, screenshots, console monitoring, network request tracking, performance metrics, accessibility tree access, debugger attachment/detachment, and multi-tab management. **Remaining gaps** — no unified cross-browser server provides consistent automation across Chrome, Firefox, and Safari through one API. Mobile browser MCP support is absent — no servers target Chrome for Android, Safari for iOS, or mobile-specific debugging. No MCP server specializes in browser extension development or testing workflows. WebMCP is advancing through W3C but not yet production-ready in stable browser releases.

ITSM & IT Service Management MCP Servers — ServiceNow, PagerDuty, Jira Service Management, Zendesk, and More

ITSM and IT service management MCP servers are one of the most mature enterprise categories, with official support from ServiceNow (native MCP in Zurich release), PagerDuty (20+ tools with read-only default safety design), Atlassian Jira Service Management (official remote MCP with on-call and alert tools), incident.io (hosted remote MCP at mcp.incident.io), FireHydrant (official open-source), and Rootly (Apache 2.0, AI-powered incident similarity analysis). ServiceNow has the richest ecosystem with native platform MCP plus 7+ community servers — echelon-ai-labs/servicenow-mcp (162 stars, role-based tool packages), Happy-Technologies happy-platform-mcp (480+ auto-generated tools from metadata across 160+ tables), ShunyaAI/snow-mcp (60+ tools), and more. PagerDuty stands out for safety-first design: read-only by default, write tools require explicit opt-in. Zendesk has strong community coverage led by reminia/zendesk-mcp-server (79 stars) but no official server. Opsgenie is covered by giantswarm/mcp-opsgenie (Go, Apache 2.0, multi-transport). Freshservice has community servers (MIT) covering tickets, changes, and assets. ManageEngine ServiceDesk Plus has PTTG-IT/SDP-MCP (16 tools, OAuth). For multi-platform ITSM, madosh/MCP-ITSM provides unified access to ServiceNow, Jira, Zendesk, Ivanti, and Cherwell through consistent tool definitions. BMC takes a different approach as an MCP client (consuming external servers via HelixGPT) rather than an MCP server. The industry is splitting between MCP server providers (exposing capabilities) and MCP client consumers (connecting their AI to external tools). Hosted remote MCP is emerging as the preferred deployment model. Notable gaps: no Squadcast, no xMatters, no SysAid MCP servers. Rating: 4.0/5 — strong official vendor adoption led by ServiceNow and PagerDuty, with the broadest enterprise coverage of any ITSM MCP category.

Publishing & Typesetting MCP Servers — LaTeX, Overleaf, Pandoc, eBooks, Print-on-Demand, InDesign, and More

Publishing and typesetting MCP servers across LaTeX/Overleaf/Typst, document format conversion, eBooks and reading, book discovery, print-on-demand, desktop publishing, and PDF tools. The document conversion subcategory remains the strongest — zcaceres/markdownify-mcp (2,600 stars, TypeScript, MIT, v1.0.4) is the standout server in the entire category, converting virtually anything (PDF, DOCX, XLSX, PPTX, images, audio, YouTube transcripts) into Markdown with 10 specialized tools, making it the de facto gateway for ingesting documents into AI workflows. vivekVells/mcp-pandoc (531 stars, Python) wraps the venerable Pandoc engine for bidirectional format conversion across Markdown, HTML, PDF, DOCX, LaTeX, EPUB, RST, and ODT — the only server offering true multi-format output including EPUB generation. The biggest change since the initial review is the arrival of johannesbrandenburger/typst-mcp (144 stars, Python, MIT, 5 tools) — Typst was explicitly called out as a missing gap, and now has an MCP server with LaTeX-to-Typst conversion, syntax validation, image rendering, and documentation access. For LaTeX, the Overleaf space has grown further — mjyoo2/OverleafMCP surged 73→110 stars (+51%), YounesBensafia/overleaf-mcp-server (26 stars, Python, MIT, read/write/sync) and gswxp2/overleaf-mcp-helper (VSCode plugin + MCP, safe editing with substring matching) both launched in March 2026, bringing total Overleaf implementations to 7+. Standalone LaTeX servers like aaronsb/texflow-mcp (22 stars) provide structured document models where AI operates on sections and paragraphs while the system handles all LaTeX mechanics. axiomlogicnexus/TeXstudio-LaTeX-MCP-Server offers the deepest IDE integration with 30+ tools including linting, formatting, bibliography management, and package installation. For academic publishing specifically, takashiishida/arxiv-latex-mcp (127 stars, MIT, v0.2.2) fetches arXiv paper LaTeX source directly — far more useful than PDF extraction for math-heavy papers. The eBook space remains rich — onebirdrocks/ebook-mcp (361 stars, Apache-2.0) provides AI-powered reading experiences with quizzes and explanations for EPUB and PDF, trieloff/calibre-mcp (30 stars) bridges Calibre's vast library management capabilities, and vgnshiyer/apple-books-mcp (48 stars, v0.7.3 April 2026) now includes chapter position tracking with 'pick up where you left off', highlight context retrieval with anchors, and reading analytics across 17 releases. andylbrummer/booklife-mcp (Go, 27 tools) unifies Hardcover, Libby/OverDrive, and Open Library into a single reading management platform. Book discovery gets two solid implementations: 8enSmith/mcp-open-library (71 stars, MIT) and mcp-google-books. Print-on-demand is an emerging niche — TSavo/printify-mcp (25 stars) integrates with Printify's platform including AI image generation via Replicate's Flux model for creating designs, while devlimelabs/lulu-print-mcp provides 20+ tools for the Lulu Print API covering print jobs, file validation, cost calculation, and shipping management. Desktop publishing has expanded — the second major gap fill is tacyan/AffinityMCP (18 stars, Rust, 9 tools), a Rust-based server for Affinity Photo/Designer/Publisher automation including file operations, document creation, export, filter application, and batch processing. Affinity Publisher was explicitly listed as missing in the initial review. zachshallbetter/indesign-mcp-server (10 stars, 135+ tools) remains the most ambitious InDesign integration, lucdesign/indesign-mcp-server (16 stars, 35+ tools) provides professional typography and EPUB export, and matrayu/adobe-mcp offers a unified server for the entire Adobe Creative Suite. Canva gets MCP integration through EmilyThaHuman/canva-mcp-server with 20 tools including AI design generation. PDF manipulation rounds out the category with hanweg/mcp-pdf-tools (74 stars) for merging, extracting, and searching PDFs, plus 2b3pro/markdown2pdf-mcp (34 stars) for generating PDFs with syntax highlighting and Mermaid diagrams. The category earns 4/5, upgraded from 3.5 — two explicitly-called-out gaps have been filled (Typst at 144 stars, Affinity Publisher at 18 stars), markdownify-mcp and mcp-pandoc remain best-in-class document conversion infrastructure, OverleafMCP surged 51% in popularity, Apple Books MCP got a major update with chapter tracking, and the academic publishing pipeline (arXiv → LaTeX → Typst → PDF) is now significantly stronger. Remaining deductions for continued Overleaf fragmentation (now 7+ servers), no EPUB authoring tools (only reading), no Amazon KDP integration, no newspaper/magazine layout tools, and desktop publishing still platform-limited despite Affinity filling the Adobe-only gap.
