AST MCP Server
About
By transforming source code into a queryable Semantic Graph and a structured AST, this tool bridges the gap between "reading text" and "understanding structure." For an AI assistant, it provides the "spatial" awareness needed to navigate deep dependencies without getting lost in

Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
AST MCP ServerCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Requires Python 3.9+ and either uv (recommended) or pip. Clone the repository, run uv sync then uv run build-parsers. Configure Claude Desktop by editing its configuration file and adding an MCP server entry with the absolute path to the server directory. Claude can then use tools like parse_to_ast, generate_asg, analyze_code, etc. to analyze code snippets or local files.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.
