## Documentation & README

# Agent Handoff Middleware

Serverless middleware for AI agent handoffs with built-in Stripe metered billing. Clean, enrich, and route messages between AI agents in one API call.

## Live API

```bash
https://agent-handoff-production-573c.up.railway.app
```bash

## Endpoints

| Endpoint | Method | Description |
|----------|--------|-------------|
| /handoff | POST | Process and route a message to the next agent |
| /health | GET | Service health check |
| /stats | GET | Usage statistics (requires API key) |
| /mcp | POST | Model Context Protocol server (`handoff` + `get_usage_stats` tools) — same auth/billing path as REST |

## Recent changes (2026-07-27)

- **MCP server added** at `POST /mcp` — exposes `handoff` and `get_usage_stats` as MCP tools over JSON-RPC 2.0, discoverable via `tools/list`. Runs through the exact same auth → usage → billing path as the REST `/handoff` endpoint, so it can't become an unmetered bypass. `server.json` added for the official MCP registry (schema-validated); publishing via `mcp-publisher` is still pending.
- **Durable billing-failure audit trail** — failures now persist to Supabase (`public.billing_failures`) instead of only an ephemeral local file that reset on every redeploy.
