An MCP server to show AI coding agents how to use a compiled java class

TJMCP is an MCP server that lets Agents know about compiled Java classes, by using:

• Java Class File API to extract low level information about the class file.
• Ollama for local inference, to interpret the low level details and generate a report of the given class.

The result is a Markdown document describing the class, generated locally without having to expose your private code to a remote LLM.

You can read more about this project in my article: An MCP Server To Describe Java Classes

How to use it

1. Build the project:

   mvn clean install

2. Add the following configuration to your agent:

   {
     "tjmcp": {
       "command": "/path/to/java",
       "args": [
         "-jar",
         "/path/to/project/target/tjmcp-0.1.jar"
       ],
       "env": {
         "TJMCP_CACHE_FOLDER": "/home/nacho/tjmcp-cache",
         "TJMCP_LANGCHAIN4J_OLLAMA_URL": "http://localhost:11434",
         "TJMCP_LANGCHAIN4J_OLLAMA_MODEL": "qwen3-coder:latest"
       },
       "timeout": 300
     }
   }
