🛠️ Configuration

MCP Settings for Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "typescript-project-indexer": {
      "command": "npx",
      "args": [
        "-y",
        "ts-project-indexer-mcp"
      ],
      "env": {}
    }
  }
}

MCP Settings for Cline

Add to your MCP configuration:

{
  "typescript-project-indexer": {
    "autoApprove": [
      "analyze_project",
      "search_methods", 
      "get_project_files",
      "get_project_stats",
      "find_usages"
    ],
    "disabled": false,
    "timeout": 60,
    "type": "stdio",
    "command": "npx",
    "args": [
      "-y", 
      "ts-project-indexer-mcp"
    ]
  }
}

Alternative: Local Installation

If you prefer to install globally:

npm install -g ts-project-indexer-mcp

Then use:

{
  "mcpServers": {
    "typescript-project-indexer": {
      "command": "ts-project-indexer",
      "args": [],
      "env": {}
    }
  }
}

⚠️ Important Change in v1.1.0: Project paths are no longer passed as command line arguments. Instead, use the analyze_project tool with an absolute projectPath parameter.

🎯 Usage Examples

Basic Project Analysis

// Analyze a specific project (absolute path required)
await mcp.callTool('analyze_project', {
  projectPath: '/home/user/my-project',
  includePatterns: ['**/*.ts', '**/*.js'],
  excludePatterns: ['node_modules/**', 'dist/**']
});

// Windows example
await mcp.callTool('analyze_project', {
  projectPath: 'C:\\Users\\user\\my-project',
  includePatterns: ['**/*.ts', '**/*.js'],
  excludePatterns: ['node_modules/**', 'dist/**']
});

Search for Methods

// Find all functions containing 'config'
await mcp.callTool('search_methods', {
  query: 'config',
  type: 'function',
  includeUsages: true
});

Find Usage Locations

// Find where a file is imported
await mcp.callTool('find_usages', {
  filePath: 'src/config.ts',
  searchType: 'imports',
  includeDetails: true
});

Get Project Statistics

// Get comprehensive project stats
await mcp.callTool('get_project_stats', {});

🔧 Available Tools

analyze_project

Analyzes and indexes the entire project structure.

Parameters:

• projectPath (string, required): Absolute path to project root (e.g., /home/user/project or C:\Users\user\project)
• includePatterns (array): File patterns to include (default: ['**/*.ts', '**/*.js', '**/*.json'])
• excludePatterns (array): File patterns to exclude (default: ['node_modules/**', 'dist/**', '**/*.d.ts'])
• forceReindex (boolean): Force full reindexing (default: false)

⚠️ Important: The projectPath parameter is required and must be an absolute path. Relative paths are not supported for security and reliability reasons.

search_methods

Search for methods, functions, and classes in the project.

Parameters:

• query (string): Search query (required)
• type (string): Type filter (method, function, class, interface, type, all)
• includeUsages (boolean): Include usage locations (default: false)

find_usages

Find where a file, method, or class is imported or used.

Parameters:

• filePath (string): Path to file to find imports/usages for
• methodName (string): Name of method/function to find usages for
• className (string): Name of class to find usages for
• searchType (string): Search type (imports, usages, both)
• includeDetails (boolean): Include detailed context (default: true)

get_project_files

Get list of all indexed project files with metadata.

get_project_stats

Get comprehensive project statistics.

debug_dependencies

Debug dependencies to see what is being indexed.

Parameters:

• limit (number): Maximum dependencies to show (default: 20)
• filterBy (string): Filter dependencies by string match

📚 Resources

project://files

List of all indexed project files with metadata.

project://methods

Index of all methods, functions, and classes.
