What is the MCP server?

The MCP server is a tool that allows you to quickly search for and analyze patterns in codebases. It leverages the powerful capabilities of ast-grep to parse and manipulate code structures.

How to use the MCP server?

You need to install the necessary software (such as ast-grep and Cursor), and then configure the MCP client. After the configuration is complete, you can start using Cursor AI to perform search tasks.

Applicable scenarios

The MCP server is very suitable for developers to find specific code patterns, refactor code, or conduct code reviews in large codebases.

Main Features

Code pattern search
Supports searching for specific patterns in code through syntax rules.
Multi-language support
Supports code parsing and searching in multiple programming languages.
Integration with Cursor
Seamlessly integrates into Cursor AI for easy direct invocation by developers.
Advantages
Efficiently search for code patterns
Support multiple programming languages
Be compatible with mainstream development tools
Limitations
May require a certain learning cost for complex queries
Depend on local environment configuration

How to Use

Install necessary software
Make sure ast-grep and Cursor are installed.
Clone and run the MCP server
Clone this repository and run the MCP server locally.
Configure the MCP client
Edit Cursor's MCP configuration file and specify the server address.

Usage Examples

Find unused variables
Quickly locate unused variables in the code through the MCP server and Cursor AI.
Refactor code
Use the MCP server to batch replace specific code patterns.
