excalidraw-mcp-lives-in-opt-mcp-servers-not-opt-infra
Excalidraw is at /opt/mcp-servers/excalidraw-mcp/, NOT /opt/infra/. Architecture.md had a misleading entry placing it under infrastructure services. Excalidraw is an MCP permanent server, not an infra service — it belongs in the MCP section, not the Infra section.
