status: candidate
notes: 'IMPORTANT CAVEAT: ON24 ships no MCP server. This crosswalk maps the CANDIDATE tool surface in mcp/on24-mcp.yml
  onto the real REST contract, so the binding is exact (every row is 1:1 against a verified operationId) but the
  MCP side is proposed, not deployed. There is no GraphQL surface. Because the tools are derived FROM the OpenAPI
  rather than observed from a live tools/list, there are no mcp_only rows by construction — that is a property of
  the derivation, not a finding about ON24.'
