Environment Variables

PORT default 3000
DATA_DIR default /data
MCP_API_KEY required in production (NODE_ENV=production)
PUBLIC_MCP_DISCOVERY default true
PUBLIC_BASE_URL optional, used for absolute links in discovery files

Local Run

Terminal

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 PUBLIC_MCP_DISCOVERY=true.
tools/call requires valid upstream auth when MCP_API_KEY is set:
- Authorization: Bearer <MCP_API_KEY> or
- x-api-key: <MCP_API_KEY>

Xpay + Railway Configuration (Required)

Railway variables:

MCP_API_KEY=<your-strong-key>
PUBLIC_MCP_DISCOVERY=true
PUBLIC_BASE_URL=https://handoff-mcp-server-production.up.railway.app

Xpay MCP URL:

Use https://handoff-mcp-server-production.mcp.xpay.sh/mcp?key=xpay_sk_...
Without ?key=..., Xpay returns auth required and requests will not forward.

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 MCP_API_KEY).
