Overview

What is mcmodding-mcp?

mcmodding-mcp is a Model Context Protocol (MCP) server that gives AI assistants direct access to up-to-date Minecraft modding documentation for Fabric and NeoForge. It enables AI tools to search real documentation, find code examples, and explain modding concepts without relying on outdated training data.

How to use mcmodding-mcp?

Install globally with npm install -g mcmodding-mcp, then add "command": "mcmodding-mcp" to your MCP client configuration (e.g., Claude Desktop). Optionally include the provided system prompt to instruct the AI to always use the server’s tools instead of internal knowledge.

Frequently asked questions

What documentation sources does mcmodding-mcp index?

It indexes the Fabric Wiki (wiki.fabricmc.net), Official Fabric Docs (docs.fabricmc.net), and NeoForge Docs (docs.neoforged.net), totaling over 1,000 pages.

How does the auto-update system work?

On startup, the server compares the local database version against GitHub releases. If a newer version exists, it downloads the update with hash verification, creates a backup, and applies the changes – all without blocking the server.

What runtime dependencies are required?

The server requires Node.js and is installed via npm. It uses local SQLite (better-sqlite3) and Transformers.js for embeddings, so no external services are needed.

Can I disable automatic updates?

Yes, set the `DB_PATH` environment variable to a custom database file path. The server will then skip auto-updates for that file.

How do the search tools work?

The server provides four tools: `search_fabric_docs` (with filters for category, loader, version), `get_example` (code examples by topic), `explain_fabric_concept` (detailed explanations), and `get_minecraft_version` (version info). They run over stdio transport.
