Email is the most sensitive data most people have. Bank confirmations, medical records, password resets, private conversations — it’s all in your inbox. Giving an AI agent access to it deserves serious thought.
That said, the use cases are compelling. An agent that can search your email for a specific receipt, draft a reply to a client, or triage your inbox by priority could save hours per week. The Gmail MCP ecosystem is trying to make this happen, with varying degrees of maturity and security. Part of our Communication & Collaboration MCP category.
The Landscape
The Gmail MCP ecosystem took another major step forward in May 2026. Google shipped a dedicated Gmail MCP server with its own endpoint and nine documented tools — this is no longer “Gmail bundled into Workspace MCP.” At Google Cloud Next ‘26 (May 19, 2026), Google announced 50+ Google-managed MCP servers now in GA or preview. The landscape includes:
- Google’s dedicated Gmail MCP server —
gmailmcp.googleapis.com, nine tools, developer preview (announced via Google Cloud Next ‘26) - Google’s official MCP servers — the google/mcp repository (4,100 stars, 48 commits) covers Workspace, Cloud, Maps, Firebase, and more
- taylorwilsdon/google_workspace_mcp — the dominant community server (2,400 stars, v1.21.0), covering 12 Google services
- MarkusPfundstein/mcp-gsuite — a focused Gmail + Calendar server (486 stars, now dormant)
- 61+ Gmail MCP servers on PulseMCP — from enterprise-grade to minimal single-purpose tools
Google’s Dedicated Gmail MCP Server
What it is: Announced as part of Google Cloud Next ‘26 (May 19, 2026), Google now operates a dedicated Gmail MCP server at gmailmcp.googleapis.com. This is distinct from the broader Workspace MCP endpoint — it is purpose-built for Gmail, with its own documentation, its own OAuth scopes, and nine specific tools.
The nine tools:
| Tool | What it does |
|---|---|
create_draft |
Create a new Gmail draft |
create_label |
Create a new label |
get_thread |
Retrieve a full email thread |
label_message |
Apply a label to a message |
label_thread |
Apply a label to a thread |
list_drafts |
List existing drafts |
list_labels |
List all Gmail labels |
search_threads |
Search threads by query |
unlabel_message / unlabel_thread |
Remove labels |
OAuth scopes: Two scopes offered — gmail.readonly and gmail.compose. This is a meaningful improvement over most community servers that request gmail.modify (full read/write/delete). The official server’s scope design limits blast radius by default.
Supported clients: Gemini CLI, Claude (Enterprise/Pro/Max/Team plans), and generic MCP clients via HTTP transport.
The security caveat: Google’s own documentation explicitly warns about indirect prompt injection — hidden instructions embedded in emails that could hijack an agent session. From the official docs: “Users should be cautious with untrusted inputs and avoid asking their MCP client to process emails from unverified sources.” This is the most explicit mainstream acknowledgment of this attack vector we’ve seen in first-party MCP documentation.
The catch: Nine tools is a narrower set than taylorwilsdon’s community server. Notable absences: send email, reply, add/remove labels from messages (only create label), attachment handling. This is developer preview — expect the tool set to expand.
Google’s Workspace MCP (google/mcp)
What it is: The google/mcp repository (4,100 stars, up from 3,900 in April, 48 commits) serves as the umbrella catalog for 14+ remote Google-managed and 14+ open-source MCP servers. Gmail via the Google Workspace endpoint (https://workspace-developer.goog/mcp) remains the broader alternative to the dedicated Gmail server — it covers Gmail, Drive, Calendar, Chat, and People in one endpoint.
Google Cloud Next ‘26 update (May 19, 2026): 50+ Google-managed MCP servers are now in GA or developer preview. The Workspace MCP server — covering Gmail profile access, drafting, searching, and read/write — is in public developer preview as of May 1, 2026 rollout.
Google API quota changes (May 1, 2026): Google introduced a standardized tiering model for Workspace agent tools and APIs. New projects from May 1 face revised quotas; existing projects were grandfathered through April. Later in 2026, Google Cloud billing enablement will be required for quota increases above standard thresholds (90 days’ notice before charges apply). Google estimates less than 1% of active developers will need to exceed the standard tier — but it’s worth knowing this is coming.
taylorwilsdon/google_workspace_mcp — The Community Standard
What it is: The most popular Google Workspace MCP server by a wide margin. google_workspace_mcp (2,400 stars, up from 2,200 in April — +9% in four weeks) covers 12 Google services with 100+ tools total. Now at v1.21.0 (released May 17, 2026), up from v1.19.0 on April 15.
Gmail tools:
| Tool | What it does |
|---|---|
| Search messages | Gmail query syntax (from:, subject:, has:attachment, etc.) |
| Get message content | Full email body, headers, metadata |
| Send email | New messages with recipients, subject, body |
| Reply to email | Reply to existing threads |
| Create draft | New drafts and reply drafts |
| List labels | All Gmail labels (system + custom) |
| Create/update/delete labels | Full label management |
| Add/remove labels | Apply or remove labels from messages |
| Gmail signature | Read/write email signatures (added v1.20.3) |
Releases since April 22:
v1.20.3 (May 1): Gmail signature support, sheet duplication, enhanced MCP tool annotations.
v1.20.4 (May 7): Configurable API retry logic, per-request impersonation for service accounts, shared drives enumeration, Slides API validation improvements.
v1.21.0 (May 17): Windows filename sanitization for Gmail attachments, defensive parsing for malformed calendar date/time inputs, OAuth token passthrough mode (operate without sharing Google OAuth client secrets — a significant security improvement), extended contact field support with merge/replace/remove modes, OAuth port auto-resolution for multi-process conflicts, richer file permission metadata.
Setup: pip install workspace-mcp or Docker. Supports OAuth 2.1 with remote multi-user capability. Also has a 1-click Claude Desktop install option.
What works: The three-tier tool system (Core/Extended/Full) lets you start with read-only access and expand as trust builds. v1.21.0’s OAuth token passthrough mode is a meaningful security improvement — you can now use the server without exposing your OAuth client secrets to the server operator. Active maintenance with near-weekly releases.
What doesn’t: The breadth is also a risk. Installing this server gives the OAuth token access to 12 Google services. If you only need Gmail, you’re granting permissions you don’t need. The gmail.modify scope is powerful — an agent with this access can delete emails, not just read them.
MarkusPfundstein/mcp-gsuite — Now Dormant
What it is: mcp-gsuite (486 stars, unchanged from April) covers Gmail and Google Calendar only. As of May 2026, however, the repository has been dormant for over a year — the last commit was April 14, 2025, over 13 months ago.
Gmail tools: Query emails, get email by ID, create draft, delete draft, reply to emails, save attachments.
The problem: With Google’s own dedicated Gmail MCP server now in developer preview and taylorwilsdon’s server shipping near-weekly updates, mcp-gsuite’s value proposition — narrow scope, fewer permissions — has been partially superseded. For narrow-scope Gmail access, Google’s official server now offers gmail.readonly and gmail.compose scopes with first-party code.
Still worth knowing: The tool set covers common operations. If you have an existing deployment, it likely still works. But for new setups, we’d recommend Google’s dedicated Gmail server or taylorwilsdon’s server over a 13-month-dormant codebase.
Gmail-Only Servers
ArtyMcLabin/Gmail-MCP-Server (Active Fork)
The original GongRzhe/Gmail-MCP-Server (1,100 stars, 344 forks) was officially archived on March 3, 2026 — permanently read-only. The ArtyMcLabin fork (now 152 stars, up from 116 in April — +31%) is the active continuation.
Original tools: Send email (plain text, HTML, multipart + attachments), create draft, get email by ID, search emails, add/remove labels, create/update/delete labels, batch processing (up to 50 emails at once).
ArtyMcLabin fork additions: Thread-level operations (get_thread, list_inbox_threads, modify_thread), complete draft lifecycle (send_draft, update_draft, delete_draft), reply-all with automatic threading header management, phishing reporting via Gmail API, custom OAuth2 scoping with --scopes flag, security hardening (path traversal fixes, credential file permission restrictions), email download in JSON/EML/TXT/HTML formats without consuming LLM context, CC/BCC visibility in email reading, tool annotations for safer LLM execution.
Install: npm install @gongrzhe/server-gmail-mcp (also available via Smithery).
Notable: The ArtyMcLabin fork continues to add features the original never shipped. If you liked the original, the fork is a clear upgrade. Do not use the original — it is archived and will receive no further updates.
baryhuang/mcp-headless-gmail
What it is: mcp-headless-gmail (53 stars) is designed for server/container deployments where no browser is available for OAuth flow.
Why it’s interesting: The decoupled credential model — OAuth flow completed by any client, credentials passed as context — is a genuine security advantage for multi-user or containerized setups. Most Gmail MCP servers assume you have a browser for the OAuth dance.
Tools: Get recent emails (first 1K chars), get full email body (chunked with offset), send emails, token refresh. Minimal but functional.
shinzo-labs/gmail-mcp
gmail-mcp (41 stars, up from 34 in March — +21%) attempts full Gmail API coverage — messages, threads, labels, drafts, settings, push notifications, and profile retrieval. Install via npx. The settings and push notification management tools are broader than most servers offer, which means broader permissions required.
Zapier Gmail MCP
Zapier now offers a Gmail MCP server at https://zapier.com/mcp/gmail. As a managed service, it abstracts OAuth setup behind Zapier’s existing account infrastructure. Worth knowing for users already in the Zapier ecosystem.
Other Servers
- theposch/gmail-mcp (17 stars) — minimal server with send and read. GPL-3.0 licensed.
- cafferychen777/gmail-mcp — Chrome extension approach. No OAuth setup needed (uses browser session), but only works with a running Chrome instance.
- david-strejc/gmail-mcp-server — uses IMAP/SMTP instead of the Gmail API. Works with app-specific passwords. Theoretically works with any IMAP email provider, not just Gmail.
The Security Question
Gmail MCP servers deserve more security scrutiny than most MCP categories. Here’s why:
Prompt injection risk (newly documented). Google’s official Gmail MCP documentation now explicitly warns about indirect prompt injection — hidden instructions embedded in email content that could hijack an agent session. This is the most prominent mainstream acknowledgment of this attack vector in first-party MCP documentation. The risk is real: an email from an attacker could contain instructions that cause your agent to forward, delete, or exfiltrate other emails.
OAuth scope creep. Most community servers request gmail.modify or even the full mail.google.com scope — read, write, send, and delete access. Few servers offer a read-only mode. Google’s dedicated Gmail server is a notable exception: gmail.readonly and gmail.compose scopes are offered separately.
Token storage. OAuth refresh tokens are typically stored in local files. If your machine is compromised, your email is compromised. The headless-gmail server’s decoupled model and taylorwilsdon’s v1.21.0 OAuth token passthrough mode are notable exceptions.
Send permission. An AI agent that can send emails on your behalf is powerful and dangerous. A hallucinated email sent to the wrong person could cause real damage. There’s no “undo send” via the API.
API quota changes. Google’s new tiering model (effective May 1, 2026) affects community server deployments. New projects face revised quotas. Heavy automation use cases should check whether they’ll hit standard tier limits.
Our recommendation: Google’s dedicated Gmail MCP server is now the strongest option for most users — first-party code, minimal scopes (gmail.readonly or gmail.compose), Google’s security model, and explicit prompt injection guidance in the docs. For broader Google Workspace needs with full control, taylorwilsdon’s server with v1.21.0’s OAuth token passthrough is the next best option. Whichever server you choose: start read-only, review prompt injection risk before letting agents process emails from untrusted senders.
Which One Should You Use?
For maximum trust + minimal scope: Google’s dedicated Gmail MCP server (gmailmcp.googleapis.com). First-party code, granular OAuth scopes, Google’s security infrastructure, explicit prompt injection guidance. The nine-tool set is narrower than community options — for most use cases, it’s enough.
For full Gmail + Workspace integration: taylorwilsdon/google_workspace_mcp is the default community choice. Largest community, most active development, broadest feature set, tiered permissions, and now OAuth token passthrough mode in v1.21.0.
For server/headless deployments: baryhuang/mcp-headless-gmail is purpose-built for environments without a browser.
For the GongRzhe replacement: ArtyMcLabin/Gmail-MCP-Server — same codebase lineage with substantial feature additions and active maintenance.
For Zapier users: Zapier’s Gmail MCP at zapier.com/mcp/gmail abstracts OAuth setup behind your existing Zapier account.
Avoid: The original GongRzhe/Gmail-MCP-Server (archived March 3, 2026). The MarkusPfundstein/mcp-gsuite server for new deployments (13+ months dormant with no commits since April 2025).

The Bottom Line
The Gmail MCP ecosystem made its most significant structural advance since Google’s April 21 announcement: Google now operates a dedicated Gmail MCP server (gmailmcp.googleapis.com) with its own endpoint, documentation, and nine specific tools. This is no longer Gmail-as-afterthought bundled into a Workspace endpoint. The explicit OAuth scope design (gmail.readonly / gmail.compose) and the direct prompt injection warning in Google’s documentation represent the most security-conscious first-party MCP offering in this category to date.
taylorwilsdon’s community server continues to lead on features — v1.21.0’s OAuth token passthrough mode addresses one of the most persistent security objections to community-operated servers. The ArtyMcLabin fork keeps growing (+31% in four weeks) as the GongRzhe successor.
The notable downgrade: mcp-gsuite is now 13 months dormant. For new deployments, Google’s dedicated server replaces it as the narrow-scope option.
But this is still the category where security matters most. Your email is the skeleton key to your digital life. Google’s own documentation now acknowledges the most dangerous threat — prompt injection via email content. Read it. Plan for it. Start read-only.
Rating: 4.0/5 — Held at 4.0. Google’s dedicated Gmail MCP with granular scopes and explicit security documentation advances the trust story materially. taylorwilsdon’s v1.21.0 OAuth token passthrough is a meaningful improvement. Offset by mcp-gsuite going dormant and the newly-documented prompt injection risk being a genuine, not-yet-solved threat. The ceiling to 4.5 requires: dedicated server tool set expansion (send + reply), prompt injection mitigations in first-party tooling, and resolution of the Google API quota tiering impact on real-world deployments.
