Features

• Generate directory tree structure
• Analyze JavaScript/TypeScript and Python files
• Extract code symbols (functions, variables, classes, imports, exports)
• Compatible with the MCP protocol for seamless integration with AI assistants

Quick Usage (MCP Setup)

Windows

{
  "mcpServers": {
    "code-context-provider-mcp": {
      "command": "cmd.exe",
      "args": [
        "/c",
        "npx",
        "-y",
        "code-context-provider-mcp@latest"
      ]
    }
  }
}

MacOS/Linux

{
  "mcpServers": {
    "code-context-provider-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "code-context-provider-mcp@latest"
      ]
    }
  }
}

OR install globally with npm:

npm install -g code-context-provider-mcp

Then use it by running:

code-context-provider-mcp # if you're not using @latest, you may want to clear the cache for latest version using `Remove-Item -Path "$env:LOCALAPPDATA\npm-cache\_npx" -Recurse -Force` for windows and `rm -rf ~/.npm/_npx` for linux/macos

Available Tools

get_code_context

Analyzes a directory and returns its structure along with code symbols (optional).

Parameters:

• absolutePath (string, required): Absolute path to the directory to analyze
• analyzeJs (boolean, optional): Whether to analyze JavaScript/TypeScript and Python files (default: false)
• includeSymbols (boolean, optional): Whether to include code symbols in the response (default: false)
• symbolType (enum, optional): Type of symbols to include if includeSymbols is true (options: 'functions', 'variables', 'classes', 'imports', 'exports', 'all', default: 'all')
• filePatterns (array of strings, optional): File patterns to analyze (e.g. ['.js', '.py', 'config.*'])
• maxDepth (number, optional): Maximum directory depth to analyze (default: 5 levels)

Note: Anonymous functions are automatically filtered out of the results.

Example Output Text On Tool Call

Directory structure for: C:\Users\Admin\Desktop\mcp\context-provider-mcp

Code Analysis Summary:
- Files analyzed: 3
- Total functions: 29
- Total variables: 162
- Total classes: 0

Note: Symbol analysis is supported for JavaScript/TypeScript (.js, .jsx, .ts, .tsx) and Python (.py) files only.

Code analysis limited to a maximum depth of 5 directory levels (default).

├── index.js (39 KB)

File Pattern Examples

You can use the filePatterns parameter to specify which files to analyze. This is useful for complex projects with multiple languages or specific files of interest.

Examples:

• ["*.js", "*.py"] - Analyze all JavaScript and Python files
• ["config.*"] - Analyze all configuration files regardless of extension
• ["package.json", "*.config.js"] - Analyze package.json and any JavaScript config files
• [".ts", ".tsx", ".py"] - Analyze TypeScript and Python files (using extension format)

The file pattern matching supports:

• Simple glob patterns with wildcards (*)
• Direct file extensions (with or without the dot)
• Exact file names

Handling Large Projects

For very large projects, you can use the maxDepth parameter to limit how deeply the tool will traverse directories:

• maxDepth: 2 - Only analyze the root directory and one level of subdirectories
• maxDepth: 3 - Analyze the root, and two levels of subdirectories
• maxDepth: 0 - Only analyze files in the root directory

This is particularly useful when:

• Working with large monorepos
• Analyzing projects with many dependencies
• Focusing only on the main source code and not third-party libraries

Supported Languages

Code symbol analysis is supported for:

• JavaScript (.js)
• JSX (.jsx)
• TypeScript (.ts)
• TSX (.tsx)
• Python (.py)

Using the filePatterns parameter allows you to include other file types in the directory structure, though symbolic analysis may be limited.

Development

Setting up the Development Environment

# Clone the repository
git clone https://github.com/your-username/code-context-provider-mcp.git
cd code-context-provider-mcp

# Install dependencies
npm install

# Set up WASM parsers
npm run setup

Post-Installation

After installation, the package's prepare script automatically runs to download the WASM parsers. If for some reason the download fails, users can manually run the setup:

npx code-context-provider-mcp-setup
