Summary
The Agent Connection Telemetry policy tracks the number of requests and what source makes the request to agent or MCP server instance.
To track the source of the request, the policy uses a DataWeave expression to extract an identification value from a request header. By default, the policy extracts the X-AGENT-ID header. The X-AGENT-ID header contains the Mulesoft instance ID.
To track the requests, the policy uses the mulesoft_agent_connection_count(source, destination) metric. Where source is the identification value extracted from the request header and destination is the agent or MCP server instance ID. Use Anypoint Monitoring to view the metric.
If the policy can’t extract the identification header, the policy doesn’t block or track the request.
| The Agent Connection Telemetry policy is applied by default to all agent and MCP server instances created using Agent Fabric. |
