AI and MCP

MCP tools

Every tool the MCP server offers, with the scope it needs and its arguments. Generated from the server's source.

A key sees only the tools its scopes allow. Tools return text: JSON for structured results, Markdown for pages. Failures come back as tool results with isError set.

Every tool, with the scope it needs, its arguments and a request to copy, is in the API reference.

Connector tools

With connectors:read, every enabled connector adds its cached tools, named <slug>__<tool>: the connector's slug, two underscores, and the tool's own name with characters other than letters, digits, _ and - replaced by _, cut at 64 characters. Their descriptions and arguments are the connector's own.

At most 200 connector tools are added per key, from the oldest connector on. If two tools end up with the same name, the first keeps it.
