@striderlabs/mcp-gmail

MCP server that gives AI agents the ability to send, read, and search email via Gmail.

For Agents

Agents use this connector to handle email autonomously on behalf of their human — reading important messages, searching for information, composing thoughtful replies, and sending communications.

Example agent workflows:

  1. Triage emails: Agent reads new messages, summarizes important ones, and flags urgent items for user attention
  2. Answer routine questions: Agent searches email history to find information, composes replies with context from past conversations
  3. Send on behalf: Agent drafts and sends professional emails based on user intent ("Let the team know I'll be late"), then logs a copy to the conversation

Usage example:

User: "Has anyone replied to my email about the Q2 budget proposal?"

Agent:

  1. gmail_search → "to:me subject:budget"
  2. gmail_read → Read each message
  3. Return summary: "Sarah replied yes on Monday. Mark asked for revisions. No word from Finance yet."

Then agent might automatically draft a follow-up to Finance and ask for approval before sending.
