What is an MCP Server?

Last updated

A server that implements the Model Context Protocol, exposing data and tools to MCP-compatible AI clients.

An MCP server is what AI tools like Claude Desktop connect to in order to access external context. Wire automatically creates an MCP server for each context container, with custom tools tailored to your data. Your AI tools can browse, search, and query your context without any manual configuration.
