Overview

What is Inbox MCP?

Inbox MCP transforms your email inbox into an intelligent, LLM-powered assistant. Built on the Nylas v3 API, it lets you manage, organize, and streamline email using conversational language with batch-friendly tools. It works out of the box with Gmail, Outlook, iCloud, Yahoo, and any IMAP service.

How to use Inbox MCP?

Install via the Smithery CLI (npx -y @smithery/cli@latest install "@darinkishore/inbox-mcp" --client claude) or manually by cloning the repo, building with npm, and configuring the MCP client’s mcp-config.json with NYLAS_ACCESS_TOKEN and NYLAS_GRANT_ID environment variables. You first need a Nylas account (free tier available) with an API key and a Grant ID from a connected email account.

Key features of Inbox MCP

  • Search emails with simple keyword queries
