Compliance & Audit MCP Servers — Vanta, Drata, SentinelGate, Agentic Gateway Registry, and More

Compliance and audit is one of the most critical — and most underdeveloped — categories in the MCP ecosystem. Enterprises deploying MCP servers face a predictable set of compliance requirements: audit trails (what did the AI agent do?), policy enforcement (what is the agent allowed to do?), access controls (who authorized the agent?), and compliance evidence (can we prove we’re meeting SOC 2, HIPAA, GDPR, ISO 27001?). The tools in this category attempt to solve these problems from different angles. Part of our Security & Compliance MCP category.

The landscape divides into six areas: compliance automation platforms (Vanta, Secureframe — query your compliance status through MCP), MCP policy enforcement (SentinelGate, Agent Identity Protocol — intercept and control tool calls), MCP monitoring (MCP Snitch, MCP Audit Extension — observe and log agent behavior), MCP gateways with audit (Microsoft MCP Gateway, Lasso MCP Gateway, Agentic MCP Gateway Registry — enterprise-grade routing with built-in audit trails), MCP security auditing (mcpserver-audit, mcp-security-audit — analyze MCP server code for vulnerabilities), and security standards (MCP Server Security Standard — certification framework for MCP servers).

The headline finding: this category is maturing unevenly — the leaders are pulling ahead while the long tail stagnates. The Agentic MCP Gateway Registry remains the clear enterprise governance leader (862 stars, Apache 2.0), now at v1.29.0 after v1.23–v1.24.1 delivered Splunk JSON Lines audit logging, local stdio server support, server-side OAuth session store, per-server encrypted HTTP headers, IPv6 dual-stack, and 5-tier cloud provider detection. Microsoft MCP Gateway (783 stars) added an agent/session subsystem in May. The compliance platform subcategory covers three vendors: Vanta (formerly the strongest open-source server, 64 stars, 13 tools — archived by the owner in June 2026), Drata (official hosted server with read-write access), and Secureframe (read-only, 8 stars — archived July 2026, deprecated in favor of a hosted server at mcp.secureframe.com). apisec-inc/mcp-audit (152 stars) expanded from config scanning to source code attack-chain detection. However, monitoring tools (MCP Snitch, MCP Audit Extension) and several gateways (Lasso) remain dormant, and the SentinelGate repo referenced in our original review is no longer reachable on GitHub (see below). The main gap is still maturity — but the category leaders are now clearly enterprise-ready.

Compliance Automation Platforms

Vanta

VantaInc/vanta-mcp-server (64 stars, TypeScript, MIT, 96 commits) is Vanta’s official MCP server. Thirteen consolidated tools cover the full compliance lifecycle:

Tests and test entities — query automated security tests and their status across compliance frameworks. Controls — manage security controls and their associated documentation. Documents — enumerate compliance documents and evidence. Integrations — explore connected service integrations and their resources. Frameworks — access framework adoption metrics and drill into specific requirements. People — personnel management and access reviews. Risk and vulnerability tracking — monitor risk scenarios with treatment plans and track vulnerabilities.

The project uses a “consolidated tool pattern” — the original design had 53 tools, reduced to 43, then consolidated further to 13 by using intelligent parameter handling. This is a smart architectural choice that keeps the tool surface manageable for LLM context windows while preserving full functionality. Recent PRs added trusted publishing and primary region routing. Correction (2026-08-14 audit): this section previously described PR #42 (adding a VANTA_MCP_ENABLED_TOOLS env var for enabling additional tools) as “open” — it was actually closed without merging on June 17, 2026, the same day the repository was archived. The repository was archived on June 17, 2026 — it is now read-only and no longer receiving updates.

Secureframe

secureframe/secureframe-mcp-server (8 stars, Python, MIT, 6 commits) is Secureframe’s official MCP server. Eleven read-only tools:

list_controls, list_tests, list_users, list_devices, list_user_accounts, list_tprm_vendors, list_vendors, list_frameworks, list_repositories, list_integration_connections, list_repository_framework_scopes.

Supports querying across SOC 2, ISO 27001, CMMC, FedRAMP, and other compliance frameworks. Uses Lucene query syntax for advanced filtering. Regional endpoint support (US and UK). Currently in public beta.

The contrast with Vanta is stark: Secureframe’s server is strictly read-only (no write operations), has far fewer commits (6 vs. 96), and covers less surface area. For querying compliance status it works, but Vanta’s server is significantly more capable. Both require paid platform subscriptions. Correction (2026-08-14 audit): this section previously said the repo was “dormant since October 2025” with the star count “slipped from 8 to 7” — the dormancy date was accurate (the last substantive commit was indeed October 8, 2025), but the star count was not: it’s held at 8, not slipped to 7. More significantly, the repo was archived on July 17, 2026: its only commit since the October 2025 dormancy is a one-line deprecation notice pointing users to a new hosted MCP server at mcp.secureframe.com, mirroring Vanta’s move away from a maintained open-source repo.

Drata

NEW. Drata — the third major compliance automation platform — now has MCP support through two routes.

Drata’s official MCP server is a proprietary hosted service (no public GitHub repo) — see Drata’s MCP configuration guide for the current documentation. Correction (2026-08-14 audit): this section previously cited modelcontextprotocol/servers PR #2157 as evidence Drata was “merged into the official MCP integrations directory,” implying a recent addition. In fact PR #2157 itself never merged — its content was folded into a batch PR, #2264, which merged on July 3, 2025 — over a year before this review, not a 2026 development. That README-based integrations list has since been retired: modelcontextprotocol/servers now points readers to the separate MCP Registry instead, and Drata does not currently appear there. Per the live help-center documentation, Drata’s official server supports read and write access, scoped to the account’s permissions: it can query and act on failing compliance tests, generate risk and controls reports, and create/update/delete evidence and controls. Confirmed frameworks include SOC 2, ISO 27001, and CCPA (the help docs don’t enumerate a complete list, so we’ve dropped this section’s earlier unconfirmed mention of HIPAA support specifically). Branded as “AI-Native Trust Management.”

sderosiaux/drata-mcp (5 stars, Python, MIT, 6 commits) is a community-built read-only alternative. Thirteen tools — all GET operations: get_compliance_summary, list_controls, list_controls_with_issues, get_control_details, get_monitors_for_control, list_monitors, list_failing_monitors, list_personnel, list_personnel_with_issues, list_policies, list_pending_policy_acknowledgments, list_connections, list_vendors. Focused on SOC 2 Type II audit preparation.

This brings the compliance platform landscape to three vendors: Vanta (formerly the most capable open-source server, 13 tools, read-write — now archived), Drata (official hosted server with read-write, community read-only alternative), and Secureframe (read-only, now archived in favor of a hosted server). All three require paid platform subscriptions.

MCP Policy Enforcement

SentinelGate

Correction (2026-08-14 audit): the Sentinel-Gate/Sentinelgate GitHub repository this section was built on no longer resolves — it now returns 404, under every case variant of the URL. The Sentinel-Gate GitHub account still exists, but its current public repositories are limited to forked “awesome-mcp-*” list projects; the actual SentinelGate product repo is gone, with no announcement, redirect, or replacement repo we could find. Third-party MCP registries (Glama, LobeHub, mcpservers.org) still mirror pages describing “SentinelGate 2.1.4” with the feature set below, but we have no live primary source to re-verify against, so treat the details in this entry as unconfirmed as of this audit — historical record of what the project described, not a current, verifiable fact.

Sentinel-Gate/Sentinelgate (Go, AGPL-3.0, reportedly v2.1.4 as of its last known state) was described as a universal firewall for AI agents that intercepts MCP tool calls and evaluates them against deterministic policies before execution.

Deterministic policy enforcement — explicit rule-based allow/deny decisions, not probabilistic AI-based filtering. This is the correct approach for compliance — auditors want deterministic controls, not “the AI thought it was probably safe.” CEL-powered rules — Common Expression Language for sophisticated policy conditions (e.g., “allow read operations on production databases only during business hours”). RBAC — role-based access control for agent identities. Complete audit trail — every action logged with identity, decision, timestamp, and arguments. Budget controls — per-identity usage limits including call caps, write restrictions, and rate limiting. Response transformation — five modification types: redaction, truncation, injection, dry-run, and masking. Session recording — full request/response capture with timeline replay and export. Admin dashboard — browser-based policy management. Policy templates — seven pre-configured security profiles. Content scanning — PII and secrets detection in tool call payloads. Platform binaries — pre-built releases for macOS, Linux, and Windows across ARM64/x86_64.

The AGPL-3.0 license may be a concern for enterprises that want to embed this as a component without open-sourcing their own code — though with the repository now gone, prospective users would need to find a live source before evaluating it at all. We’re leaving this entry in place as a record of what we reviewed, but we cannot currently recommend deploying a tool whose source repository has disappeared without explanation.

Agent Identity Protocol (AIP)

openagentidentityprotocol/agentidentityprotocol (36 stars, Go, Apache 2.0, 87 commits) is a zero-trust identity layer for MCP and autonomous agents. It provides authentication, attestation, authorization, and governance.

Agent Authentication Token (AAT) — cryptographic signing for agent identity, so every tool call is tied to a verified agent. Policy enforcement proxy — sidecar deployment that intercepts tool calls and evaluates them against YAML-based policies. DLP scanning — data loss prevention on both requests and responses, catching sensitive data before it leaks through tool calls. Human-in-the-Loop — approval dialogs for sensitive operations. Immutable JSONL audit logging — tied to agent identity for forensic traceability. Tool allowlisting — with argument validation per tool. Revocation support — through registry mechanisms.

V0.1 (Localhost Proxy) is stable. V0.2 (Kubernetes Sidecar) and v1.0 (OIDC/SPIFFE Federation) are in the roadmap. A Rust implementation is listed as “coming soon.” The 87 commits show more development maturity than most tools in this category, though no new commits since March 2026 — development appears stalled. Apache 2.0 is enterprise-friendly. Supports Cursor IDE and Claude Desktop integration.

MCP Monitoring

MCP Snitch

Adversis/mcp-snitch (94 stars, Swift, GPL-3.0, 6 commits) is a macOS application that intercepts and monitors MCP server communications.

Real-time interception — of both stdio and HTTP MCP transports. AI-powered threat detection — uses GPT-3.5 to analyze tool calls for security concerns. Pattern-based detection — for sensitive data exposure (credit cards, SSNs, API keys). Comprehensive audit logging — full request/response history. Manual and automatic approval modes — for tool calls. Automatic server discovery — reads Claude Desktop and Cursor configs to find MCP servers. Secure API key storage — via macOS Keychain.

The macOS-only limitation is significant — most production MCP deployments run on Linux servers, not developer laptops. The GPL-3.0 license (with commercial licensing available) and the reliance on GPT-3.5 for threat detection add friction. Still, for individual developers who want visibility into what their MCP servers are doing, this is the most accessible option. Only 6 commits despite 94 stars — the star count likely reflects interest in the concept more than production adoption. Dormant since October 2025 (last push October 14, 2025).

MCP Audit Extension

borisdan/mcp-audit-extension (27 stars, TypeScript, MIT, 44 commits) audits and logs all GitHub Copilot MCP tool calls in VS Code. Correction (2026-08-14 audit): this section previously listed the repo under Agentity-com/mcp-audit-extension — that GitHub organization no longer exists (404), and the repo now lives under the maintainer’s personal account, borisdan. Star count and functionality are unchanged.

Creates mirrored “(tapped)” versions of configured MCP servers for transparent auditing. Supports multiple log forwarders: Splunk HEC, CEF/Syslog, and local file logging. Includes an MCP Audit Log viewer in the VS Code Explorer sidebar. Generates structured JSON logs with tool parameters, results, and metadata. Enterprise-ready with MDM/configuration management support.

This is the right approach for enterprise adoption — log MCP tool calls to existing SIEM infrastructure (Splunk, Syslog) rather than building a new logging pipeline. The VS Code/Copilot focus is narrow but hits a large user base.

MCP Gateways with Audit

Microsoft MCP Gateway

microsoft/mcp-gateway (783 stars, C#/.NET, ~41 commits) is a reverse proxy and management layer for MCP servers in Kubernetes environments.

RESTful control plane APIs — deploy and manage MCP servers programmatically. Session-aware routing — data plane gateway with session affinity. Dynamic tool routing — Tool Gateway Router for multi-server tool aggregation. Azure Entra ID authentication — with role-based authorization. Kubernetes-native — StatefulSet-based deployment. MSRC security hardening — Kubernetes network policies, Redis credential management, and container image validation.

New in May 2026: An agent/session subsystem (preview) was added on May 18 (commit 3184d61, PR #63). New /agents and /sessions REST endpoints, a Foundry-backed AgentRunner with MCP tool loops, multi-turn SSE event streaming, and built-in bash/file tools with regex denylists and per-session disk quotas. Cosmos and in-memory storage options. Disabled by default until FoundrySettings:Endpoint is configured. Separately, an April 16 commit (#61) addressing MSRC-reported issues added Kubernetes network policies, Redis credential management, and container image validation; a May 22 fix (#79) closed an SSRF vulnerability (MSRC-112281).

Star count is now 783 (up from 599 when this review began). Microsoft’s enterprise backing and Azure Entra ID integration make this the natural choice for organizations already on Azure. The agent subsystem preview is the first sign this is evolving from pure routing/proxy into an orchestration layer.

Lasso MCP Gateway

lasso-security/mcp-gateway (385 stars, Python, MIT, 40 commits) is a plugin-based gateway that orchestrates other MCP servers with security guardrails.

Request/response sanitization — protects credentials from leaking through tool calls. Plugin architecture — four plugin options: Basic (token masking), Presidio (PII detection via Microsoft Presidio), Lasso (AI safety guardrails), and Xetrack (monitoring/tracing). Unified interface — discover and interact with proxied MCPs through a single endpoint. Security scanning — for server reputation and risk analysis.

Two tools: get_metadata (information about proxied MCPs) and run_tool (execute capabilities from any proxied MCP after sanitization). The PII detection via Microsoft Presidio is particularly relevant for GDPR compliance — it can catch personal data in MCP responses before they reach the LLM context. Latest release v1.2.0 (January 2026) added Lasso Guardrails v3 API support. No new commits since January 2026 — the repo appears to have stalled.

Agentic MCP Gateway Registry

agentic-community/mcp-gateway-registry (862 stars, Python, Apache 2.0, 30 contributors) is the most comprehensive enterprise MCP governance solution in the category. Still the standout performer — releases through v1.24.1 (April–May 2026) added Splunk integration, local stdio support, server-side OAuth session storage, and IPv6; development has continued at a fast pace since, reaching v1.29.0 on August 13, 2026 with egress-authentication hardening, application-level rate limiting, on-behalf-of token exchange, and a per-user OAuth credential vault (OpenBao/AWS Secrets Manager backends).

Multi-provider IAM — Keycloak, Microsoft Entra ID, Auth0, and Okta integration. Dynamic semantic search — across servers, tools, and agents. Virtual MCP servers — aggregating multiple backends. MCP server versioning — with instant rollback. Agent Skills Registry — reusable instruction sets with GitHub private repo auth. Comprehensive audit logging — JSON Lines format for Splunk (v1.23), SOC 2/GDPR compliance. Peer-to-peer registry federation — across instances. Security scanning — via Cisco AI Defense tools with YARA pattern matching. Agent-to-Agent (A2A) protocol support — for direct agent communication. AWS AgentCore federation — for AWS agent ecosystem. Agent Name Service — trust verification for agent identities. Registration admission webhooks — for automated approval workflows. Multi-key API auth and M2M direct registration — enterprise authentication patterns. OTLP metrics export — direct push to observability platforms.

New in v1.22–v1.24.1 (April–May 2026): Group-restricted agents and OAuth2 Client Credentials gate (v1.0.22). 5-tier cloud provider detection, strict semver (dropped v prefix), Helm extraEnv injection (v1.23). Local stdio MCP server support alongside remote HTTP servers (v1.24) — a significant architectural expansion that means any local CLI-based MCP server can now be registered and governed. Per-server custom HTTP headers encrypted at rest. Tool-level access filtering in the API. Resource-bound JWT tokens for scoped authorization. IPv6 dual-stack support. Server-side OAuth session store (v1.24.1) — session payload moved from browser cookie into MongoDB/DocumentDB, glibc CVE remediation, three new ops runbooks (MongoDB export/import, audit log retrieval, secret rotation). Breaking change: SECRET_KEY is now mandatory and OAUTH_STORE_TOKENS_IN_SESSION is removed.

DocumentDB and MongoDB CE storage backends. AWS ECS deployment with Terraform. Includes MCP Registry CLI for conversational tool discovery, IAM settings UI for user/group management. This is the closest thing to “enterprise-ready MCP governance” that exists today — and the gap between it and the rest of the category continues to widen.

MCP Security Auditing

mcpserver-audit

ModelContextProtocol-Security/mcpserver-audit (21 stars, 21 commits) is part of the Model Context Protocol Security initiative, which the project identifies as a Cloud Security Alliance community project, and audits MCP server source code for security vulnerabilities. (Correction, 2026-08-14: the table and text previously disagreed — 13 vs. 15 stars — and both were stale; current count is 21.)

Scores vulnerabilities using AIVSS (AI Vulnerability Scoring System) — a specialized scoring framework for AI-specific threats. Maps findings to CWE (Common Weakness Enumeration) categories. Integrates with audit-db (10 stars, 9 commits) — a community-maintained database of MCP server audit results and security assessments with standardized audit manifests and structured finding formats.

This is a “meta” tool — it doesn’t help with compliance of your application, it helps you evaluate whether MCP servers themselves are safe to deploy. Useful for security teams vetting MCP server adoption.

mcp-security-audit

qianniuspace/mcp-security-audit (56 stars, TypeScript, MIT, 23 commits, v1.0.4) audits npm package dependencies for security vulnerabilities.

Real-time vulnerability scanning against the remote npm registry. Detailed reports with severity classification (critical, high, moderate, low), CVSS scoring, and CVE references. Automatic fix recommendations. Compatible with npm, pnpm, and yarn. Docker support available.

A focused tool — it’s an npm audit wrapped in MCP, not a compliance platform. But dependency vulnerability management is a compliance requirement for SOC 2 and ISO 27001, so it has a legitimate place in compliance workflows.

apisec-inc/mcp-audit

apisec-inc/mcp-audit (152 stars, Python, MIT) scans MCP configurations across Claude Desktop, Cursor, VS Code, Windsurf, and Zed for security issues. Three core capabilities:

Exposed secrets scanning — detects 25+ patterns of leaked credentials in MCP server configurations. Shadow API detection — identifies undocumented or unexpected API connections from MCP servers. AI-BOM generation — produces CycloneDX 1.6 AI Bills of Materials for compliance documentation.

Output formats include JSON, CSV, Markdown, SARIF (for GitHub Security integration), and PDF. Available as both a CLI tool and web application.

New in May 2026 (v1.1): The source-scan command is a significant capability leap — it analyzes MCP server source code itself to detect Prompt-In-Shell-Out attack chains: patterns where prompt data flows through shell execution (e.g., exec(), subprocess) in ways that could enable injection attacks. Covers JavaScript/TypeScript and Python codebases, with SARIF output and CI/CD integration examples. This moves the tool from static config analysis into supply chain security of the MCP servers themselves.

Limitation (pre-v1.1): the original config scanning mode analyzes MCP config files, not runtime behavior — it catches secrets hardcoded in configs but won’t detect secrets passed at runtime. The v1.1 source-scan partially addresses this by examining the server code, not just config.

Microsoft Purview DLM Diagnostics MCP Server

NEW. microsoft/purview-dlm-mcp (9 stars, TypeScript, MIT) is Microsoft’s MCP server for diagnosing Purview Data Lifecycle Management issues. Open-sourced March 2026 (earliest commits visible March 6, 2026).

Five tools: run_powershell — execute read-only Exchange Online diagnostic commands via an allowlisted command set. get_execution_log — retrieve diagnostic execution history. ask_learn — query Microsoft Learn documentation for Purview troubleshooting. create_issue and submit_feedback — report problems to Microsoft. Includes 72 diagnostic checks and 11 troubleshooting guides covering retention policies, archiving, and compliance configuration.

Niche but significant — Purview is Microsoft’s compliance and data governance platform used by enterprises subject to regulatory data retention requirements. The read-only PowerShell approach (commands are allowlisted, not arbitrary execution) is the right security model for compliance tooling. Requires PowerShell 7 and MSAL authentication. Part of Microsoft’s broader agent security architecture where Purview enforces DLP and sensitivity labels on agent-to-agent data flows.

Lighthouse MCP Server

danielsogl/lighthouse-mcp-server enables AI agents to perform comprehensive web audits using Google Lighthouse — 13+ tools for performance, accessibility, SEO, and security analysis. Relevant for accessibility compliance (WCAG) and security auditing of web properties. Already covered in our Performance & Load Testing MCP Servers review.

Kubernetes Audit Logs

kube-audit-mcp

mozillazg/kube-audit-mcp (19 stars, Go, MIT, 46 commits, v0.4.1) enables AI agents to query Kubernetes audit logs from multiple cloud providers.

Three tools: query_audit_log — query with filtering by namespace, resource type, user, and action verbs. list_clusters — enumerate configured clusters. list_common_resource_types — display available resource types.

Multi-cloud support: AWS CloudWatch Logs, Google Cloud Logging, and Alibaba Cloud Log Service. Compatible with Claude Desktop, VS Code, Gemini CLI, and kubectl-ai. Docker containerization available. YAML-based configuration.

The tool count is small but the use case is focused — Kubernetes audit logs are a compliance requirement for SOC 2 and ISO 27001 in containerized environments. Having AI agents query these logs through natural language makes compliance investigation significantly faster.

Security Standards

MCP Server Security Standard (MSSS)

MCP Server Security Standard (74 stars, CC BY-SA 4.0 for the standard text, Apache 2.0 for schemas, MIT for code examples, 20 commits) is an open, testable security control standard for certifying MCP servers. Recent updates added a “Compliant Platforms” section, currently listing MCP-Hub as its first certified implementation.

24 security controls spanning 8 domains: Filesystem, Execution, Network, Authorization, Input Validation, Logging, Supply Chain, and Deployment. 4 compliance levels:

6 deployment profiles for various scenarios. Machine-readable reporting via JSON schemas. Evidence-based verification with clear acceptance criteria. Inspired by NIST CSF, OWASP ASVS, and CIS Controls.

This isn’t an MCP server — it’s a certification framework. But it’s the most structured attempt to define what “secure” means for MCP servers, and compliance teams evaluating MCP adoption will likely reference it. The risk-based level selection model is practical — not every MCP server needs Level 4 certification.

What’s missing

The compliance and audit MCP category still has notable gaps, though some from our original review have narrowed:

No HIPAA-specific MCP tooling — healthcare organizations deploying MCP have no purpose-built compliance tools. HIPAA’s audit trail requirements (access logs for PHI, minimum necessary access enforcement) would benefit from MCP-native implementation. The trend is toward multi-framework tools (SOC 2 + HIPAA + GDPR) rather than single-regulation servers, but none have deep HIPAA-specific functionality.

No unified compliance dashboard — Vanta, Secureframe, and now Drata solve their own platforms’ needs, but there’s no MCP server that aggregates compliance status across multiple frameworks and providers.

OPA/Rego integration emerging — Red Hat has published Claude Code skills (redhat-et/rhacm-gatekeeper-skills) for generating OPA Gatekeeper policies on OpenShift/RHACM, including NIST SP 800-53 and BSI IT-Grundschutz compliance agents. This isn’t a standalone MCP server yet, but it’s the first bridge between OPA policy-as-code and MCP-connected AI agents.

No real-time alerting — the audit tools log events, but none trigger real-time alerts when policy violations occur. SentinelGate was described as blocking violations without alerting on patterns, though see the correction above — we can no longer verify this against a live source.

No compliance-as-code for MCP — there’s no equivalent of terraform plan for MCP deployments that would show “this change will violate your SOC 2 controls.”

MCP config hygiene is now addressed — apisec-inc/mcp-audit (152 stars) fills the gap for scanning MCP configurations for exposed secrets and generating AI Bills of Materials, and has expanded into source-code attack chain detection.

Emerging: mcp-hangar — mcp-hangar/mcp-hangar (13 stars, MIT, active — now past v2.6.0, up from v1.x in our original review) is a runtime security and governance gateway for MCP servers. (Correction, 2026-08-14: this entry previously said the project was “recently relicensed from BSL 1.1 to MIT” and had “JSON Schema validation for interceptors” — we could not find a primary source for either claim in the project’s release history and have dropped them. The v1.2.3 release does confirm auth/TLS config serialization with recursive secret redaction, so that detail stays.) Worth watching — the “runtime security” gap is real, and this is one of the few projects explicitly targeting it.

The bottom line

The compliance and audit MCP category continues to address the #1 blocker for enterprise MCP adoption: governance. The Agentic MCP Gateway Registry (862 stars, active, now at v1.29.0) remains the most mature enterprise solution — this cycle it added Splunk JSON Lines audit logging, local stdio server support, server-side OAuth session storage, IPv6, resource-bound JWTs, and glibc CVE remediation, and has kept shipping since (egress hardening, rate limiting, credential vault). Microsoft MCP Gateway (783 stars) added an agent/session orchestration subsystem preview. apisec-inc/mcp-audit expanded from config scanning into source-code attack chain detection with the new source-scan command.

For enterprises evaluating MCP compliance: start with the Agentic MCP Gateway Registry for centralized governance, add Vanta or Drata MCP for compliance platform integration (note Vanta’s open-source server is now archived — the hosted platform continues), and run apisec-inc/mcp-audit to scan your MCP configurations and source code for attack patterns and generate AI-BOMs. Consider Agent Identity Protocol for zero-trust agent identity if you need cryptographic audit trails. (We’ve dropped our earlier recommendation of SentinelGate for deterministic policy enforcement — its GitHub repo is no longer reachable as of this audit; see the correction above.)

Rating: 3.5/5 — held. The leaders are getting stronger (Agentic Gateway, Microsoft MCP Gateway, apisec-inc/mcp-audit all shipped meaningful updates), but the long tail remains stagnant — MCP Snitch, Lasso, AIP, and kube-audit-mcp have all gone quiet, and SentinelGate’s repo has disappeared entirely. Vanta’s open-source server was archived in June 2026; Secureframe’s was archived in July 2026 in favor of a hosted server. The category is becoming a two-tier story: enterprise-grade leaders and a dormant (or vanished) second tier.
