This MCP server provides formal verification for Deterministic Finite State Machines (FSM) used in agent orchestration. It allows AI agents to validate workflow structures, simulate execution traces to detect livelocks or stuck states, and calculate critical metrics like state coverage and path length. Use validate_structure to ensure reachability and determinism, simulate_execution to test specific event paths, and get_workflow_metrics to assess overall workflow complexity.

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

validate_structure

Ensures the FSM is mathematically sound

get_workflow_metrics

Provides high-level FSM complexity and health metrics

simulate_execution

Evaluates a specific execution trace

See how to talk to your AI agent using Workflow State Machine Validator.

Validate this FSM structure: states=[{'id': 's1', 'type': 'START'}, {'id': 's2', 'type': 'END'}], transitions=[{'fromStateId': 's1', 'toStateId': 's2', 'condition': 'go', 'action': 'move'}]

{ "isValid": true, "errors": [], "metrics": { "orphanStateIds": [], "unreachableStateIds": [] } }

Simulate an execution where the current state is 's1' and the event is 'go'.

{ "nextStateId": "s2", "isStuck": false, "coverage": 1.0, "maxPathLength": 1, "hasLivelock": false }

Get metrics for a workflow with 3 states and 2 transitions.

{ "totalStates": 3, "totalTransitions": 2, "complexityScore": 0.66, "longestPath": 2 }

The `validate_structure` tool checks if the FSM is mathematically sound, ensuring all states are reachable from START, every state can reach an END, and transitions are deterministic.
