Extract code symbols (functions, variables, classes, imports, exports)
Compatible with the MCP protocol for seamless integration with AI assistants

Quick Usage (MCP Setup)

Installing via Smithery

To install Code Context Provider for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @AB498/code-context-provider-mcp --client claude

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)
│   └── [Analyzed: 22 functions, 150 variables, 0 classes]
│       Functions:

│       - getLanguageFromExtension [107:0]
│       - getPosition [138:24]

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
