MCP (Model Context Protocol)
MCP attaches extra tools from outside servers (GitHub, browsers, databases, internal APIs).
In the app
Settings → MCP (also under Tools). Add a server, enable it, and start a new chat so the tool list is picked up.
You can also manage GitHub, Vercel, Cloudflare, and Codemagic as first-party Settings → Connectors when you want those four without an MCP server.
Safety
Only enable servers you trust. MCP tools can read files or call APIs with the credentials you give that server. Filter or disable tools in the MCP settings row when the server exposes more than you need.
