Tools Discovery →What is the Beeline MCP Server?
A Beeline MCP server lets AI agents read and write Beeline data through the Model Context Protocol — Anthropic's open standard for connecting LLMs to external tools. StackOne's Beeline MCP server ships with 75 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 Beeline MCP Tools
Every action from Beeline's API, ready for your agent. Create, read, update, and delete — scoped to exactly what you need.
