The Plain Bytecode Analyzer MCP is a server that analyzes JVM `.class` bytecode to provide insights on performance and optimizations.

Plain Bytecode Analyzer MCP

This MCP (Model Context Protocol) server analyzes JVM .class bytecode to provide insights on performance and optimizations. It retrieves the bytecode as text of a specified class and suggests potential improvements while ensuring code legibility and efficiency.

How to install

  1. Clone the repository.
  2. Install dependencies using npm or yarn:
  3. In your preffered code editor, add this MCP server to your MCP configuration pointing to the index.js file. For example in VSCode, add the following to your mcp.json:
"bytecode-analyzer-mcp": {
  "command": "node",
  "args": [
    "/path/to/my/cloned/repo/bytecode-analyzer-mcp/index.js"
  ],
  "type": "stdio"
}

How it works

  1. By providing the source code and the class name, the MCP server uses the javap command to retrieve the bytecode of the specified class.
  2. It analyzes the bytecode to identify potential performance improvements and optimization strategies.
  3. The server returns the bytecode along with suggestions for optimization.

Future Improvements

  • Add it to a MCP Registry
  • Test with different JVM projects of different languages (Java, Kotlin, Scala, etc).
  • Add more detailed information reggarding the bytecode. For example, we can use static analysis techniques to gatter the Control Flow Graph (CFG) and Data Flow Analysis (DFA) of the bytecode. But this requires specific tooling, and maybe it should be done in a Java environment in a separate MCP server.
