HelloBooks Public MCP Server

A public, read-only Model Context Protocol server that lets AI agents answer questions about HelloBooks accurately — pricing, integrations, country support, compliance frameworks — instead of relying on stale web snippets.

This is the public server. It exposes only marketing-derived, public-domain data. The authenticated MCP server that reads a customer's books lives in AI-MCP-Hellobooks.

Security posture

• Read-only by construction. No tool mutates state. No tool reaches a customer system.
• Public data only. All catalog content is sourced from the public marketing site.
• No authentication. Intentional — this is a knowledge endpoint.
• Rate-limited. 120 req/min per IP, 60 req/min per session.
• Audit gate. npm run audit:public-data blocks deploys if any PII / auth token strings appear in src/data/.

Deployment

Containerised — see Dockerfile. Designed to run behind a TLS-terminating load balancer. Set PORT and HOST via environment.

Optional anonymous usage telemetry (Layer-2 server-side analytics) is sent to GA4 via the Measurement Protocol when GA4_MEASUREMENT_ID and GA4_API_SECRET are both set — see .env.example and src/analytics.ts. Leave them unset and the server runs with telemetry fully disabled. No customer data, request bodies, tool-argument values, or IP addresses are ever sent — only anonymous counts. See strategy doc 73.

docker build -t hellobooks-mcp-public .
