# Architecture Reference

**Canonical architecture doc:** [for-developers/ARCHITECTURE.md](../../for-developers/ARCHITECTURE.md) -- system layers, data flow, integration patterns, technology stack.

**Server details:** Each server's README in `servers/mcp-*/README.md` is the source of truth for that server's tools, parameters, and examples. See [Server Registry](../shared/server-registry.md) for the full list.
