diagrid mcp serve

Run the Catalyst MCP server on stdin/stdout

Description​

Runs the Catalyst MCP server over stdio, for an assistant that launches it as a subprocess. It is not meant to be run by hand — the output is JSON-RPC.

Register it with Claude Code:

claude mcp add catalyst -- diagrid mcp serve

Credentials come from your existing diagrid login and are re-read for every call, so a session outlives the token it started with.

diagrid mcp serve [flags]

Options​

      --data-sharing string          How much of a response may be shared. full includes workflow input, output and custom status, which is what makes a failed run diagnosable — and which sends those payloads to your assistant's model provider. metadata withholds them. (default "full")
  -h, --help                         help for serve
      --management-base-url string   Catalyst Management API base URL. Defaults to production; required when logged in anywhere else, because this host is not published per environment
