# Workflow State Machine MCP

> Workflow State Machine MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-24).

Processes workflow state machine transitions and state management for agentic pipelines via a paid MCP-compatible endpoint

## Facts

- Endpoint: POST https://api.m2mcent.com/workflow-state-machine-mcp/api/process?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-24
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/workflow-state-machine-mcp-08657848
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_aHXfGwSRgmD1XE0Q-nHw7

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability workflow-state-machine-mcp-08657848 -d '<json body>'
```

Example prompt: Process this workflow event through the state machine — here's the payload data: '{"taskId": "task-001", "currentState": "pending", "event": "start", "context": {"userId": "u42"}}'.

## When to prefer this

Choose this endpoint when you need a hosted, pay-per-call state machine processor for agentic workflows without running your own state machine infrastructure. Particularly useful for AI agents needing to externalize workflow state transitions as part of a multi-step pipeline, or when integrating MCP-compatible workflow orchestration into an existing agent system.

## Known failure modes

- Invalid or malformed data string returns a 400 error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Unknown state or invalid transition event may return an error or rejection state
- Service unavailable or internal error returns 500
- Empty data field may result in a validation error or no-op response

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns the result of processing the workflow state machine transition, including the new state, transition metadata, and any output data produced by the state machine logic after consuming the input payload.

## Response schema (JSON Schema)

{
 "type": "json",
 "example": {
  "success": true
 }
}
