Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[!WARNING] `flac-mcp` is deprecated and frozen. It is superseded by **`itasca-mcp`** — a single multi-engine MCP server covering FLAC, PFC, 3DEC, MPoint, and MassFlow. Update your MCP client config from uvx flac-mcp to uvx itasca-mcp (select FLAC docs via the software parameter). No further releases are planned here.
