Joern (Code Analysis)
Joern-MCP is a server implementation that provides AI assistants with access to Joern's code analysis capabilities through a Python interface. This server enables querying and analyzing Code Property Graphs (CPGs) by exposing tools for loading CPGs, retrieving method and class code, examining call relationships, and executing custom queries against the Joern backend. Built on the FastMCP framework, it handles communication with a remote Joern instance via HTTP requests, making it particularly valuable for security researchers and developers who need to perform static code analysis, identify vulnerabilities, or understand code structure and dependencies through AI assistants.
