Code Index MCP

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, .mjs, .cjs)
• Frontend Frameworks (.vue, .svelte, .astro)
• 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, .less, .sass, .stylus, .styl)
• Template engines (.hbs, .handlebars, .ejs, .pug)
• Database & SQL:
  • SQL files (.sql, .ddl, .dml)
  • Database-specific (.mysql, .postgresql, .psql, .sqlite, .mssql, .oracle, .ora, .db2)
  • Database objects (.proc, .procedure, .func, .function, .view, .trigger, .index)
  • Migration & tools (.migration, .seed, .fixture, .schema, .liquibase, .flyway)
  • NoSQL & modern (.cql, .cypher, .sparql, .gql)
• Documentation/Config (.md, .mdx, .json, .xml, .yml, .yaml)

Installation

Prerequisites

• Python 3.8 or higher
• uv package manager (recommended)

Using uvx (recommended)

The easiest way to install and use code-index-mcp is with uvx:

uvx code-index-mcp

Using pip

Alternatively, you can install via pip:

pip install code-index-mcp

After installation, you can run it as a module:

python -m code_index_mcp

Integration with Claude Desktop

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

{
  "mcpServers": {
    "code-index": {
      "command": "uvx",
      "args": [
        "code-index-mcp"
      ]
    }
  }
}

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.

Example Usage with Claude

Here are some examples of how to use Code Index MCP with Claude:

Setting a Project Path

Please set the project path to C:\Users\username\projects\my-python-project

Searching for Code Patterns

Search the code for all occurrences of "def process_data" in Python files

Getting a File Summary

Give me a summary of the main.py file in the project

Finding All Files of a Certain Type

Find all JavaScript files in the project

Development

Building from Source

1. Clone the repository:

git clone https://github.com/username/code-index-mcp.git
cd code-index-mcp

1. Install dependencies:

uv sync

1. Run the server locally:
