handoff-mcp-server

Durable handoffs and shared scratchpad for multi-agent workflows over MCP (HTTP transport).

Endpoints

  • GET / basic service info
  • GET /health health and storage stats
  • POST /mcp JSON-RPC MCP endpoint
  • GET /robots.txt discovery file
  • GET /llms.txt discovery file
  • GET /sitemap.xml discovery file

Environment Variables

  • PORT default 3000
  • DATA_DIR default /data
  • MCPAPIKEY required in production (NODE_ENV=production)
  • PUBLICMCPDISCOVERY default true
  • PUBLICBASEURL optional, used for absolute links in discovery files

Local Run

npm ci
npm run build
MCP_API_KEY=test-secret node dist/index.js

MCP Auth Behavior

  • Discovery methods (initialize, tools/list, resources/list, prompts/list, ping) can be public when PUBLICMCPDISCOVERY=true.
  • tools/call requires valid upstream auth when MCPAPIKEY is set:
  • Authorization: Bearer or
  • x-api-key:

Xpay + Railway Configuration (Required)

  1. Railway variables:
  • MCPAPIKEY=
  • PUBLICMCPDISCOVERY=true
  • PUBLICBASEURL=https://handoff-mcp-server-production.up.railway.app
  1. Xpay MCP URL:
  • Use https://handoff-mcp-server-production.mcp.xpay.sh/mcp?key=xpaysk...
  • Without ?key=..., Xpay returns auth required and requests will not forward.
  1. Client calls through Xpay:
  • Keep the Xpay key in URL.
  • Also send upstream auth header for tools/call (x-api-key or Bearer token matching MCPAPIKEY).
