What is a production-ready MCP server?

It's an MCP (Model Context Protocol) server using FastMCP that handles real loads: pooled async Postgres, secure tool calls, OpenTelemetry monitoring, and Kubernetes deployment—far beyond demos.

How do you secure tools in FastMCP from bad LLM prompts?

Use a YAML allowlist loaded at startup, plus @require_allowlist decorators that block unauthorized calls pre-execution. Add column whitelists for SQL safety.

Does this MCP template work with Kubernetes out of the box?

Yes—includes container Dockerfile and deployment manifests that manage secrets properly, ready to apply and scale.
