概览

What is mcp-code-search-server?

mcp-code-search-server is an MCP (Model Context Protocol) server that helps large language models (LLMs) find the location of relevant code within files and supports returning complete function definitions. It uses ripgrep to search for identifiers (variables, functions, classes, etc.) in a codebase and returns their full definitions, not just references.

How to use mcp-code-search-server?

Install with npm install mcp-code-search-server or pnpm install mcp-code-search-server. Run as a CLI tool with npx mcp-code-search-server. It can be integrated as an MCP server in LLM tools by configuring a command that launches npx -y mcp-code-search-server over stdio.

Key features of mcp-code-search-server

Searches code identifiers using ripgrep
Supports JavaScript/TypeScript, Java, and Python parsing
Extracts complete variable, function, and class definitions
Automatically detects and handles multiple file encodings (UTF-8, GBK, Big5, etc.)
Smart default filtering excludes common non-code directories and file types

Use cases of mcp-code-search-server

An LLM needs to locate and understand a specific function implementation in a large codebase
A developer uses an LLM-based coding assistant to retrieve full class definitions during refactoring
An automated code review tool searches for all usages and definitions of a variable
A language model analyzes dependencies by retrieving complete definitions of imported symbols
