概要

What is yagms?

yagms is a Gmail MCP server that provides tools to interact with your Gmail account through the Model Context Protocol (MCP). It is built with Bun and allows AI assistants to read, search, and manage Gmail data.

How to use yagms?

First, create OAuth credentials in Google Cloud Console and save them as ~/.yagms-oauth.keys.json. Then build the project with bun install and bun run build-gmail. Run bun run dist/gmail.js auth to authenticate, then start the server with bun run src/gmail.ts. Configure MCP to point to the built dist/gmail.js file.

FAQ from yagms

What dependencies does yagms require?

yagms requires Bun to build and run, and a Google Cloud project with the Gmail API enabled and OAuth 2.0 credentials.

How do I authenticate with my Gmail account?

Run bun run dist/gmail.js auth which opens a browser for Google sign-in and saves credentials to ~/.yagms-credentials.json. You can customize the paths with GMAIL_OAUTH_PATH and GMAIL_CREDENTIALS_PATH.

Where are authentication files stored?

OAuth keys default to ~/.yagms-oauth.keys.json and credentials default to ~/.yagms-credentials.json. Both paths are configurable via environment variables.

Does yagms support any transport besides stdio?

The README only shows a command-line MCP configuration using bun runtime; it does not mention HTTP or other transports. The server is designed for local stdio-based MCP communication.

What are the available tools?

yagms provides four tools: list-emails, get-email, search-emails, and get-labels. Each has documented parameters as shown in the README.
