Code Index MCP

A Model Context Protocol server for code indexing, searching, and analysis.

What is Code Index MCP?

Code Index MCP is a specialized MCP server that provides intelligent code indexing and analysis capabilities. It enables Large Language Models to interact with your code repositories, offering real-time insights and navigation through complex codebases.

This server integrates with the Model Context Protocol (MCP), a standardized way for AI models to interact with external tools and data sources.

Key Features

• Project Indexing: Recursively scans directories to build a searchable index of code files
• Code Search: Find patterns, function definitions, and references across your codebase
• File Analysis: Get detailed insights about file structure, imports, and complexity
• Smart Filtering: Automatically ignores build directories, dependencies, and non-code files
• Persistent Storage: Caches indexes for improved performance across sessions

Supported File Types

The server supports multiple programming languages and file extensions including:

• Python (.py)
• JavaScript/TypeScript (.js, .ts, .jsx, .tsx)
• Java (.java)
• C/C++ (.c, .cpp, .h, .hpp)
• C# (.cs)
• Go (.go)
• Ruby (.rb)
• PHP (.php)
• Swift (.swift)
• Kotlin (.kt)
• Rust (.rs)
• Scala (.scala)
• Shell scripts (.sh, .bash)
• Web files (.html, .css, .scss)
• Documentation/Config (.md, .json, .xml, .yml, .yaml)

Integration with Claude Desktop

Add this to your Claude settings (~/Library/Application Support/Claude/claude_desktop_config.json):

After adding the configuration, restart Claude Desktop and the Code Index MCP tools will be available.

Available Tools

Core Tools

• set_project_path: Sets the base project path for indexing.
• search_code: Searches for code matches within the indexed files.
• find_files: Finds files in the project matching a given pattern.
• get_file_summary: Gets a summary of a specific file, including line count, functions, imports, etc.
• refresh_index: Refreshes the project index.
• get_settings_info: Gets information about the project settings.

Utility Tools

• create_temp_directory: Creates the temporary directory used for storing index data.
• check_temp_directory: Checks the temporary directory used for storing index data.
• clear_settings: Clears all settings and cached data.
