# TAI42 — the OS for AI tools

> An open-source runtime for MCP tools, agents, and workflows — the server that runs them.

MCP connects tools to AI models, but it does not run them — tai is the server
that does. You bring a capability (a plain Python function, an agent, an
external MCP server) and the runtime supplies the operational layer around it:
loading everything from a manifest, access control, OAuth connectors to outside
apps, background execution, monitoring, storage, and human-in-the-loop steps.
Everything plugs in against a shared set of interfaces, so anyone can extend it,
and each install is a self-contained system you host yourself.
