call_site_connector

io.github.valetdotdev/valet · Verify this server

Run one tool on a connector attached to a website and return what the connector answered. It is the sampling step of building a page that calls live data: discover, attach, read the schemas, then call one tool for real before you write any page code. Call it because a schema is not a shape. list_site_connectors gives you each tool's name and argument schema, which is what your call has to satisfy; this tells you what comes back, which is what the page has to parse. Results are text to read, not JSON to assume: many servers answer in markdown tables or prose, some expose a single meta-tool taking a whole command as one string, and a server that completes the handshake can still refuse half its tools when the stored credential's scope does not cover them. One real call settles all three. This runs the tool for real, with the organization's own credential and whatever side effects the tool has. It is not a dry run and there is no preview: a tool that sends, writes, or deletes will do so. Prefer a read-only tool when you are only learning the shape, and ask the user before running anything that changes their systems. The connector must already be attached to the site — attach_site_connector does that — and must be an HTTP MCP server. A tool that answers with an error is reported as an error carrying the connector's own text, which is usually the sentence that says what to fix. Requires connecting a Valet account.
