JEBMCP Server

Overview of JEBMCP

JEBMCP bridges two powerful ecosystems—JEB, a commercial reverse‑engineering framework, and Minecraft Coder Pack (MCP), the de facto toolkit for Minecraft modding. By exposing JEB’s analysis capabilities through MCP’s scripting and resource layers, the server allows an AI assistant to query decompiled code, invoke JEB’s analysis passes, and manipulate the resulting artifacts directly within a Minecraft modding workflow. This integration removes the need to manually export binaries or switch contexts, streamlining the reverse‑engineering process for both seasoned analysts and mod developers.

The server implements a set of MCP resources that represent decompiled classes, methods, and metadata extracted by JEB. Each resource can be queried or updated via the MCP protocol, enabling an AI to request a specific class, inspect its bytecode, or trigger a JEB‑based refactoring pass. The tools exposed by the server perform common reverse‑engineering tasks such as deobfuscation, signature extraction, and dependency graph generation. These tools can be invoked from the AI’s prompt engine, allowing the assistant to automate repetitive analysis steps and surface insights without leaving the conversation.

Key capabilities include:

• Seamless data flow: JEB’s output is automatically wrapped into MCP‑compatible JSON, so the AI can treat decompiled artifacts as first‑class data objects.
• Customizable analysis pipelines: Developers can extend the server with additional JEB scripts, exposing new tools that fit niche use cases (e.g., anti‑debug checks or custom bytecode transformations).
• Efficient resource handling: The server caches frequently accessed classes, reducing latency for repeated queries and keeping the AI’s interactions snappy.
• Cross‑platform compatibility: Because MCP is language‑agnostic, the server can serve clients written in Python, JavaScript, or any other environment that speaks MCP.

Real‑world scenarios where JEBMCP shines include:

• Modding legacy Minecraft versions: Analysts can decompile the obfuscated game jar with JEB, then use MCP tools to map names and generate modding APIs automatically.
• Security research: Researchers can quickly iterate on malware samples, pulling decompiled code into the AI for threat analysis or automated patch generation.
• Educational projects: Instructors can provide students with a hands‑on reverse‑engineering environment where the AI guides them through dissecting and modifying bytecode.

Integrating JEBMCP into an AI workflow is straightforward: the assistant connects to the server via the MCP protocol, requests a resource or tool, and receives structured data in return. The AI can then present summaries, generate patch scripts, or even suggest refactoring strategies—all without leaving the chat interface. This tight coupling reduces context switching and accelerates the time from discovery to actionable insight.

In summary, JEBMCP offers a unique convergence of reverse‑engineering precision and modding flexibility. By exposing JEB’s analytical power through MCP, it empowers developers to automate complex decompilation tasks, enrich AI‑driven code analysis, and accelerate the creation of high‑quality Minecraft mods or security solutions.
