namespace · packages/agent-mcp/src/jsonRpc.ts:41

const jsonRpcCode = {
  PARSE_ERROR,
  INVALID_REQUEST,
  METHOD_NOT_FOUND,
  INVALID_PARAMS,
  INTERNAL_ERROR,
  REQUEST_FAILED,
}

The codes MCP relies on.

INVALID_PARAMS is the one that carries meaning here: the spec puts an unknown tool and arguments that fail the advertised schema on this side, and everything the application decided -- unavailable, unauthorized, cancelled -- in a result with isError.
