This MCP server provides essential validation for LlamaIndex Workflow event routing, ensuring your agentic orchestrations are free of unhandled emissions. By using validate_routing_logic, you can detect dead-end loops where an emitted event has no registered handler, preventing autonomous agents from hanging indefinitely. The trace_workflow_trajectory tool allows you to map the exact sequence of events from any starting point, while audit_event_coverage identifies orphan handlers that are unreachable within your workflow graph.

3 tools expose this connector's capabilities to your AI agent.

audit_event_coverage

Pass the definitions as a JSON string. Audit the coverage and connectivity of event-driven steps

trace_workflow_trajectory

Pass the definitions as a JSON string and the name of the origin event. Trace the execution path of a workflow starting from a specific event

validate_routing_logic

Pass the event definitions as a JSON string. Validate the routing configuration for event-driven workflows

See how to talk to your AI agent using LlamaIndex Workflow Event Router Validator.

Check if my workflow configuration is safe from dead-end loops.

The routing logic is valid; all events emitted by your steps have registered handlers in the registry.

Trace the path starting from the 'start_event' in my LlamaIndex workflow.

The execution path is: start_event -> process_data -> end_event.

Are there any unreachable handlers in my current event registry?

There are 2 isolated steps that are part of the registry but cannot be reached from any entry point.

The `validate_routing_logic` tool identifies events that are emitted but have no registered handler, which would otherwise cause an agent to wait indefinitely for a trigger that never arrives.
