- Converts code into UML diagrams and flowcharts.
- Supports C#, JavaScript, Python, TypeScript, C, and C++.
- Uses TreeSitter for parsing and Mermaid/D3 for visualization.
- Offers two MCP tools: analysis and retrieval.
- Can be tried online or run locally as an MCP server.
- Integrates with Ollama for AI-assisted analysis.
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
SCASTCommand (node, npx, python, etc.)nodeArguments-
Argument 1
/YOUR_INSTALL_DIR/SCAST/mcp/index.js -
Argument 2
/YOUR_WORKSPACE/ -
Argument 3
C:\Users\DKZ\OTHER_ALLOWED_DIR\
Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
-
Argument 1
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Clone the repository, run npm install, then configure the MCP server in your AI client with the command node and the path to /YOUR_INSTALL_DIR/SCAST/mcp/index.js followed by one or more allowed workspace directories. The server exposes two tools: scast_analysis for generating diagrams and keyword explanations, and scast_retriever for searching code definitions.
scast_analysis
Assist users in analyzing and summarizing code through visualization by providing the folder path. Generates an AST tree, various visual charts (UML diagrams, AST tree diagrams, and Mermaid flowcharts), and returns a keyword list containing all class and method names with functionality explanations.
scast_retriever
Helps users analyze and summarize code by providing the file path of the source code folder. Performs static analysis and generates an AST tree. Allows searching using keywords (class name, method name, or field name) in the AST tree to find the source code at its definition.

The underlying principle involves leveraging a parser to parse the code into an Abstract Syntax Tree (AST), followed by static analysis, and finally utilizingMermaidandD3for visualization.

SCAST is a tool designed to assist users in analyzing and summarizing code through visualization. By simply providing the folder path where the code is located, SCAST can perform static analysis on the code, generating an AST tree to helping users understand the code structure and explain its functionality. Generate various visual charts such as UML diagrams, AST tree diagrams and Mermaid flowcharts. Finally return a keyword list containing all class and method names along with their functionality explanations, and include a link to allow users to view the chart details in their browser.
SCAST is a tool that helps users analyze and summarize code and provides visualizations. You need to provide the file path of the source code folder. SCAST will perform static analysis on the source codes in the folder, generating an AST tree to help users understand the code structure and explain its functionality. After analyzing the code directory with SCAST, you can use keywords in the AST tree for searching, better answering user questions using a RAG method. This keyword can be a class name, method name, or field name. SCAST will find the source code at its definition and return it.
