Google Workspace MCP Documentation

Current reference for authentication, transport modes, CLI usage, and all Google Workspace tool groups.

Authentication

Legacy OAuth 2.0 and OAuth 2.1 multi-user flows, including stateless and external-provider modes.

Source: auth/

OAuth 2.1 (Multi-User)

Enable with `MCP_ENABLE_OAUTH21=true` and run HTTP transport (`--transport streamable-http`). This is the recommended mode for modern MCP clients and bearer-token auth.

ParameterRequiredDescription
MCP_ENABLE_OAUTH21RequiredSet to `true` to enable OAuth 2.1 mode.
--transport streamable-httpRequiredRequired transport for OAuth 2.1 and full MCP compliance.

Legacy OAuth 2.0 (Single-User / Fallback)

Default mode when OAuth 2.1 is not enabled. Use this for older clients that do not support OAuth 2.1. `--single-user` cannot be combined with OAuth 2.1.

ParameterRequiredDescription
--single-userOptionalLegacy single-user flow; mutually exclusive with OAuth 2.1.
OAUTHLIB_INSECURE_TRANSPORTOptionalSet to `1` only for local HTTP development callbacks.

Stateless Mode

Container-friendly mode with no filesystem writes. Requires OAuth 2.1 and bearer tokens on requests.

ParameterRequiredDescription
WORKSPACE_MCP_STATELESS_MODERequiredSet to `true` (requires OAuth 2.1).

External OAuth 2.1 Provider

Use when your app handles OAuth externally. The server skips local OAuth flow and validates incoming bearer tokens.

ParameterRequiredDescription
EXTERNAL_OAUTH21_PROVIDERRequiredSet to `true` with `MCP_ENABLE_OAUTH21=true`.

OAuth Proxy Storage Backends

Select proxy storage backend for OAuth state in distributed deployments.

ParameterRequiredDescription
WORKSPACE_MCP_OAUTH_PROXY_STORAGE_BACKENDOptionalOne of `memory`, `disk`, or `valkey`.
WORKSPACE_MCP_OAUTH_PROXY_DISK_DIRECTORYOptionalDisk backend path.
WORKSPACE_MCP_OAUTH_PROXY_VALKEY_HOSTOptionalValkey/Redis host for distributed storage.

Server Modes and CLI

Transport guidance, CLI mode, tool tiers, and permission filtering options.

Source: main.py

HTTP Transport (Recommended)

Run with `--transport streamable-http` for Claude Code, VS Code MCP, MCP Inspector, and OAuth 2.1 support.

Stdio Transport (Legacy)

Use only for clients with incomplete MCP support. Not recommended for modern multi-user flows.

CLI Mode (`--cli`)

Directly list and invoke tools from the command line without running the full MCP server process.

ParameterRequiredDescription
--cli list --jsonOptionalList tools for scripting and automation.
--cli <tool> --args <json>OptionalInvoke a specific tool with JSON args.

Tool Tiers

Three cumulative tiers for simplified deployments: `core`, `extended`, `complete`.

ParameterRequiredDescription
--tool-tier core|extended|completeOptionalScope loaded tools to the selected tier.

Read-Only and Granular Permissions

`--read-only` requests readonly scopes and hides write tools. `--permissions` enables per-service permission levels.

ParameterRequiredDescription
--read-onlyOptionalRequests readonly scopes and filters write tools.
--permissions service:levelOptionalPer-service access levels (for example `gmail:send`).

Reverse Proxy OAuth URL Overrides

Use external URL overrides when running behind a reverse proxy so generated OAuth endpoints match public domains.

ParameterRequiredDescription
WORKSPACE_EXTERNAL_URLOptionalSets a public base URL for OAuth-related endpoints.
GOOGLE_OAUTH_REDIRECT_URIOptionalOverride only the OAuth callback URL.
OAUTH_CUSTOM_REDIRECT_URISOptionalComma-separated additional redirect URIs.
