Every response includes both human-readable text and structured JSON.

Programmatic key generation

Agents that hit the MCP server without a token receive a JSON response explaining how to get one. The key generation endpoint is rate-limited to 1 key per IP per day.

# Request without auth → server tells you how to get a key
curl -X POST https://mcp.slashr.dev/mcp
