}Agents
Check an assigned plugin connection
Checks that the engine can reach an assigned plugin. A failed check returns 200 with safe failure categories; an unavailable engine returns ENGINE_ERROR.
- MCP server: the engine connects with anonymous access, the Bearer or API key credential the plugin sends or its valid OAuth authorization, lists the tools without calling them, then closes the client. The credential and its resolved value are checked again before success.
- HTTP API on Main executor: the engine opens a connection to the base URL, sends no request and uses no credential; tool_count is 0.
- HTTP API on a cluster: not checked here, and the result is a failure. Check it from the plugin page in Command Center, where the check runs in the cluster.
- Disabled assignments may be checked without enabling them, except a hosted MCP server: the check starts it, so only a tenant-level administrator may check one that is turned off (403).
