# ClosedMCP

> ClosedMCP is one MCP connection to the tools a company allows each person. Every call runs as the signed-in person and is audited. Companies can also have ClosedMCP host MCP servers they write (Serverless MCPs).

These pages are plain markdown, the same text the `closedmcp_guide` MCP tool returns for each topic.
