Quick Start

• Using CLI (recommended):
  • Authorize: uvx google-docs-mcp auth authorize [-f|--force]
  • Start server (default stdio): uvx google-docs-mcp server [--transport stdio|http|sse|streamable-http]
• Using local instance:
  • Authorize: uv run google_docs_mcp auth authorize
  • Start server: uv run google_docs_mcp server

MCP Config (example)

Add to your MCP client configuration (installed CLI):

[mcp_servers.google_docs_mcp]
command = "uvx"
args = ["google-docs-mcp", "server"]
env = {
  WRITE_MODE = "disabled",
  GOOGLE__CLIENT_ID = "<id>",
  GOOGLE__CLIENT_SECRET = "<secret>",
}

OAuth Setup

1. Create OAuth Desktop client in Google Cloud Console.
2. Provide GOOGLE__CLIENT_ID and GOOGLE__CLIENT_SECRET as env vars, or put a client file in the config dir and set GOOGLE__OAUTH_CLIENT_FILE.
3. Run google-docs-mcp auth authorize (or uv run -m google_docs_mcp.cli auth authorize) and approve scopes.

Write Safety

• Controlled via WRITE_MODE env var. Default is enabled. Set disabled to block any write tools.

Configuration

• This repo provides an auto-generated Configuration.md and a starter .env.example. They are the source of truth for all env vars and defaults.
• Common variables:
  • WRITE_MODE: enabled (default) or disabled
  • LOG_LEVEL: DEBUG | INFO (default) | WARNING | ERROR | CRITICAL
  • GOOGLE__CLIENT_ID, GOOGLE__CLIENT_SECRET, GOOGLE__OAUTH_CLIENT_FILE, GOOGLE__SCOPES s See Configuration.md for all environment variables and examples. A starter .env.example is provided.

Notes

• Python 3.13, pydantic v2, ruff format, strict mypy.
• No tests by design; keep code small and documented.

MCP Inspector

The MCP Inspector is a handy UI to explore and call tools.

Interactive setup (recommended):

• Start Inspector: npx -y @modelcontextprotocol/inspector
• In the connection dialog, set:
  • Transport: stdio
  • Command: google-docs-mcp (or uv for the alternative config above)
  • Args: server
  • Env (optional): add WRITE_MODE=disabled and your OAuth vars if not already stored
• Connect, then list tools and try docs.from_url and docs.read.

Tip: enable verbose logs with LOG_LEVEL=DEBUG in Env to diagnose issues.

Note on Drive permissions

• Some tools (comments and exports) call the Drive API. If you see a Drive 404 like "File not found" on an accessible Doc, re-authorize with Drive read-only scope:
  • Ensure GOOGLE__SCOPES includes https://www.googleapis.com/auth/drive.readonly.
  • Run google-docs-mcp auth authorize again to grant the new scope.

Diagnostics

• Show token info (safe): google-docs-mcp auth token-info
• Revoke local token: google-docs-mcp auth revoke

Security

• Required scopes: https://www.googleapis.com/auth/documents and https://www.googleapis.com/auth/drive.readonly.
• Secrets are never logged. The mcp://token-info resource exposes only safe metadata.
