## Description

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.

## Tools

### validate_structure
Ensures the FSM is mathematically sound

### simulate_execution
Evaluates a specific execution trace

### get_workflow_metrics
Provides high-level FSM complexity and health metrics

## Prompt Examples

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

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

**Prompt:** 
```
Simulate an execution where the current state is 's1' and the event is 'go'.
```

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

**Prompt:** 
```
Get metrics for a workflow with 3 states and 2 transitions.
```

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

## Frequently Asked Questions

**What does `validate_structure` do?**
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.

**How can I detect if a workflow is stuck?**
You can use `simulate_execution` to run a specific event through the machine. If the `isStuck` flag is true, it means the current state has no valid transition for that event.

**Can I measure the complexity of my workflow?**
Yes, the `get_workflow_metrics` tool provides a complexity score and the longest path length to help you understand the workflow's depth and density.
