Basecamp MCP Server

Model Context Protocol (MCP) server for Basecamp integration. Enables LLMs to interact with Basecamp projects, messages, todos, comments, people, and kanban boards.

Getting Started

The Basecamp MCP server requires Node.js 18+ and works with various MCP clients including Claude Code CLI, Claude Desktop, Cursor, VS Code, and others.

Standard Configuration

The baseline setup applies across most tools:

{
  "mcpServers": {
    "basecamp": {
      "command": "npx",
      "args": ["-y", "basecamp-mcp@latest"],
      "env": {
        "BASECAMP_CLIENT_ID": "your_client_id",
        "BASECAMP_CLIENT_SECRET": "your_client_secret",

        "BASECAMP_USER_AGENT": "YourApp (your@email.com)",
        "BASECAMP_ACCOUNT_ID": "account_id"
      }
    }
  }
}
