claude-search-mcp

This MCP (Model Context Protocol) server provides web search capabilities using the Claude API. It allows LLMs to access up-to-date information from the web through a standardized interface.

• Web search tool using Claude's web search API
• Support for domain filtering (allowed and blocked domains)
• Configurable maximum results per search
• Automatic configuration from Claude Desktop config file

• Node.js 18 or higher
• An Anthropic API key with web search enabled
• Claude Desktop app for testing

1. Clone the repository:

   git clone https://github.com/Doriandarko/claude-search-mcp.git
   cd claude-search-mcp

2. Install dependencies:

   npm install

3. Build the server:

   npm run build

   This compiles the TypeScript code and makes the server executable.

4. Link the server for global access:

   npm link

   This makes the mcp-server-claude-search command available system-wide, allowing the Claude Desktop app to find it.

Once the server is installed and linked, the Claude Desktop app can manage it automatically if configured correctly.

1. Configure Claude Desktop App: Open your Claude Desktop app's MCP server configuration file (usually claude_desktop_config.json). Add or update the entry for this server:

   {
     "mcpServers": {
       // ... other servers ...
       "claude-search": {
         "command": "mcp-server-claude-search",
         "env": {
           "ANTHROPIC_API_KEY": "YOUR_ANTHROPIC_API_KEY_HERE"
         }
       }
       // ... other servers ...
     }
   }

   Replace "YOUR_ANTHROPIC_API_KEY_HERE" with your actual Anthropic API key. The server will also attempt to read this key from ~/code/claude-search-mcp/claude_desktop_config.json if the env variable is not set here, but it's good practice to define it per-server in the main config.

2. Launch Claude Desktop App: Start (or restart) your Claude Desktop application. It should now be able to find and launch the mcp-server-claude-search when needed.

3. Use Web Search: You can now use web search capabilities in your conversations with Claude.

If you want to run the server manually for testing or development purposes (outside of the Claude Desktop app management):

• Using the globally linked command:

  mcp-server-claude-search

• Directly with tsx (for development with auto-restart):

  npm run dev

• Running the compiled code directly:

  npm start

The web search tool supports the following parameters when called by an LLM:

• query (required): The search query string.
• maxResults (optional): Maximum number of search results to return (default: 5).
• allowedDomains (optional): Array of domains to include in search results (e.g., ["example.com", "wikipedia.org"]).
• blockedDomains (optional): Array of domains to exclude from search results.
