MCP server for editing EA College Football 27 dynasty and Madden NFL franchise save files - LLM tooling built on bep713/madden-franchise

About franchise-mcp-server

An MCP (Model Context Protocol) server that lets LLMs read and edit Madden NFL franchise saves and EA SPORTS College Football dynasty saves (CFB 27+). It wraps bep713/madden-franchise — the community-standard parser behind tools like Franchise Editor — and exposes its full capability as a set of well-guarded tools. It also reaches the Frostbite game-asset layer (textures/meshes/tuning inside the game files) via a headless Frosty sidecar — see Frostbite game-asset layer.

Supported games (inherited from the library): Madden 19–27, College Football 27+. Both franchise saves and FTC (franchise-common) game-data files open.

This server depends on madden-franchise via file:../madden-franchise — clone it as a sibling directory (the repo version includes CFB 27 support that is ahead of the npm release):

Register with Claude Code (project .mcp.json)
