Minecraft Mod Documentation MCP Server

The MCP Server for Minecraft Mod Documentation addresses a common bottleneck in mod development: quick, reliable access to the latest API references and best‑practice guides across multiple loader versions. Modders frequently juggle between Neoforge, Fabric, and other loaders, each with its own versioned documentation set. Manually navigating online repositories or downloading large archives is tedious and error‑prone, especially when a new version is released. This server centralizes those resources, automatically keeping local caches up to date and exposing them through the Model Context Protocol so that AI assistants can retrieve, parse, and present information in real time.

At its core, the server implements three high‑level tools that mirror a typical developer workflow. First, lists all available documentation providers (e.g., Neoforge) and the specific loader versions they support. Second, returns a hierarchical view of a chosen version’s file tree, accompanied by short previews of each document; this allows an assistant to surface the most relevant sections without downloading entire files. Finally, delivers the complete text of any selected document, enabling detailed explanations or code snippets to be pulled directly into a conversation. By automating repository updates—triggered on first use or after 24 hours—the server guarantees that assistants always reference the latest API changes without manual intervention.

The value proposition extends beyond mere convenience. AI workflows can now query the server to answer questions like “How do I register a custom block in Neoforge 1.21?” or “What are the differences between and in Fabric 0.15?” The assistant can retrieve the precise section, embed it into a response, and even suggest code snippets that align with the current API. This tight integration reduces context switching for developers, keeps them focused on coding rather than hunting down docs, and helps prevent version‑specific bugs that arise from outdated knowledge.

Real‑world scenarios where this MCP server shines include onboarding new team members, rapid prototyping of mod features, and troubleshooting compatibility issues across loader versions. For instance, a junior developer can ask the assistant to fetch the latest “Entity” registration guide for Neoforge 1.20.6, while a senior modder can use the server to compare migration steps between Fabric 0.14 and 0.15 during a major update. Because the server exposes its capabilities through standard MCP, any client that supports the protocol—Claude Desktop, VS Code extensions, or custom IDE plugins—can seamlessly incorporate up‑to‑date documentation into their toolchain.

Unique advantages of this implementation include its lightweight, Python‑based architecture that requires no external database, and the built‑in cache management which minimizes bandwidth usage. Additionally, the modular provider design means new loaders can be added with minimal effort, ensuring that the server grows alongside the modding ecosystem. By bridging the gap between static documentation and dynamic AI assistance, this MCP server empowers developers to write cleaner, version‑aware code faster than ever before.
