# btca Docs

> Set up btca for local repo search, cloud workflows, and MCP-powered agents.

btca is a codebase research tool with three main entry points: CLI, web app, and MCP. Use
these docs to install it, add resources, configure providers, and connect your coding tools.

Use the guides to get set up, then jump into the API reference for exact request and
response shapes.
