MCP Server
MCP tool provider
A small service that exposes tools and data to a model through the Model Context Protocol — query a database, read Linear issues, search docs — so the harness does not need custom integration per service.
Concrete example
An MCP server wraps your Postgres schema; the agent calls list_tables and run_query through MCP.
Why it matters
The plug-in layer for serious agent workflows.
