fn register_mcp_catalog_probe(engine: &Arc<WshRpcEngine>, state: &AppState)Expand description
Health/prerequisite probe for a global catalog server, callable without
an agent context (mirrors mcp.catalog.*’s window-scoped, no-check_s1
shape) — this is what lets Connectors → MCP servers show a
connected/error status per row before any agent has bound the server.
