Tools Discovery →What is the Basecamp MCP Server?
A Basecamp MCP server lets AI agents read and write Basecamp data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Basecamp MCP server ships with 133 pre-built actions, fully extensible via the Connector Builder — plus managed authentication, prompt injection defense, observability, and agent execution runtime. Connect it from MCP clients like Claude Desktop, Claude Code, Cursor, Goose, and VS Code, or from agent frameworks like OpenAI Agents SDK, LangChain, and Vercel AI SDK.
All Basecamp MCP Tools
Every action from Basecamp's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
