Apache 2.0
Allows cloning and processing of local git repositories, extracting code context from different branches and files for semantic search.
Code Context MCP Server
A Model Context Protocol (MCP) server for providing code context from local git repositories. This server allows you to:
Clone git repositories locally
Process branches and files
Generate embeddings for code chunks
Perform semantic search over code
Features
Uses local git repositories instead of GitHub API
Stores data in SQLite database
Splits code into semantic chunks
Generates embeddings for code chunks using Ollama
Provides semantic search over code
Prerequisites
Node.js (v16+)
Git
Ollama with an embedding model
Installation
# Clone the repository
git clone <repository-url>
cd code-context-mcp
# Install dependencies
npm install
# Build the project
npm run build
Configuration
Set the following environment variables:
DATA_DIR: Directory for SQLite database (default: '~/.codeContextMcp/data')REPO_CACHE_DIR: Directory for cloned repositories (default: '~/.codeContextMcp/repos')
Using Ollama
For faster and more powerful embeddings, you can use Ollama:
# Install Ollama from https://ollama.ai/
# Pull an embedding model (unclemusclez/jina-embeddings-v2-base-code is recommended)
ollama pull unclemusclez/jina-embeddings-v2-base-code
Usage
Using with Claude Desktop
Add the following configuration to your Claude Desktop configuration file (claude_desktop_config.json):
{
"mcpServers": {
"code-context-mcp": {
"command": "/path/to/your/node",
"args": ["/path/to/code-context-mcp/dist/index.js"]
}
}
}
Tools
The server provides the following tool:
queryRepo
Clones a repository, processes code, and performs semantic search:
{
"repoUrl": "https://github.com/username/repo.git",
"branch": "main", // Optional - defaults to repository's default branch
"query": "Your search query",
"keywords": ["keyword1", "keyword2"], // Optional - filter results by keywords
"filePatterns": ["**/*.ts", "src/*.js"], // Optional - filter files by glob patterns
"excludePatterns": ["**/node_modules/**"], // Optional - exclude files by glob patterns
"limit": 10 // Optional - number of results to return, default: 10
}
The branch parameter is optional. If not provided, the tool will automatically use the repository's default branch.
The keywords parameter is optional. If provided, the results will be filtered to only include chunks that contain at least one of the specified keywords (case-insensitive matching).
The filePatterns and excludePatterns parameters are optional. They allow you to filter which files are processed and searched using glob patterns (e.g., **/*.ts for all TypeScript files).
Database Schema
The server uses SQLite with the following schema:
repository: Stores information about repositoriesbranch: Stores information about branchesfile: Stores information about filesbranch_file_association: Associates files with branchesfile_chunk: Stores code chunks and their embeddings

This server cannot be installed
local-only server
The server can only run on the client's local machine because it depends on local resources.
An MCP server that provides semantic search over local git repositories, enabling users to clone repositories, process branches, and search code through vectorized code chunks.
