Sourcebot exposes each tool an owner has [allowed](https://docs.sourcebot.dev/docs/features/connectors/tool-permissions.md), named with its connector's name as a prefix. The prefix keeps tools from different connectors apart. Your tool list updates within a few seconds when you connect or disconnect a connector, or when an owner changes a tool's permission, adds or removes a connector, or enables or disables the MCP Gateway or a connector. This needs an MCP client that supports tool list updates, such as Claude Code. With other clients, reconnect to see the change. Parameters: the connector's own parameters for that tool. ## `connect_connector` Signs you in to a connector you haven't connected yet, or whose sign-in expired. Sourcebot asks you to confirm before starting the connector's sign-in, so the sign-in link carries no credentials. * **Clients that support URL elicitation**, such as Claude Code and VS Code, open the sign-in for you. Your agent waits until you finish, then carries on with the connector's tools. * **Other clients** show you the sign-in link to open in your browser. Tell your agent when you're done. If a connector's sign-in expires while you're using it, clients that support URL elicitation also open the sign-in for you, and the tool call continues once you've signed in. Sourcebot only offers this tool when there's a connector you can connect. Parameters: | Name | Required | Description | | :- | :- | :- | | `connector` | no | The connector to connect. Leave it out to list the connectors you can connect. | This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
