Basecamp MCP Server (2026 Complete)
by BusyBee3333
If you or your team live in Basecamp, this is the MCP server you have been waiting for. Basecamp MCP Server (2026 Complete) from BusyBee3333 exposes 100+ tools covering the full Basecamp 3 API to Claude, Cursor, Copilot, and any MCP-compatible client.Projects. To-dos. Messageboards. Schedules. Card Tables. Documents. Chat. All of it, behind a clean MCP interface that any agent can call.Why It MattersBasecamp is the project management app that refuses to die — 75,000+ companies still run their work on it. But the Basecamp API has been an integration desert for years. Zapier connectors are limited. Official integrations are sparse. And until now, no complete MCP server existed.This one is complete. 100+ tools. MCP v2.1. OAuth 2.1 baked in. Streamable HTTP transport for remote hosting. The timing is perfect — MCP v2.1 just landed with first-class OAuth and streamable HTTP, which means you can host this server behind your team's SSO and let every agent on your stack use it.Installgit clone https://github.com/BusyBee3333/basecamp-mcp-2026-complete cd basecamp-mcp-2026-complete npm install cp .env.example .env # add Basecamp OAuth credentials npm run build npm startThen add to your MCP client config (Claude Desktop, Cursor, or Claude Code .mcp.json).RelatedPair this with Rowboat for knowledge-graph meeting capture that writes directly into Basecamp to-dos.
