Prerequisites: Setting Up for Fetch MCP Server + Claude Desktop

Prepare your environment to ensure a smooth setup.

1. Node.js

   • Required: Node.js v16 or higher.
   • Check with node --version or download from nodejs.org.

2. Claude Desktop

   • Download from anthropic.com.
   • MCP integration requires a paid plan (Max, Team, or Enterprise).

3. Project Workspace

   • Open your terminal and create a dedicated folder:

     mkdir fetch-mcp-project
     cd fetch-mcp-project
     

   • This will house your Fetch MCP setup.

Step 1: Installing Fetch MCP Server

Integrate Fetch MCP server into your environment by following these steps:

1. Clone the Repository

git clone https://github.com/zcaceres/fetch-mcp.git
cd fetch-mcp

This pulls the latest Fetch MCP server code from GitHub.

2. Install Dependencies & Build

npm install
npm run build

• Installs necessary Node.js packages (e.g., sharp for image processing).
• Builds the server for use.

3. Configure Claude Desktop

• Locate the Claude Desktop config file:
  • On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Or via app: Settings > Developer > Edit Config

• Add the Fetch MCP server configuration:

  {
    "mcpServers": {
      "fetch": {
        "command": "node",
        "args": ["{ABSOLUTE PATH TO FILE HERE}/dist/index.js"]
      }
    }
  }
  

  Replace {ABSOLUTE PATH TO FILE HERE} with the actual path to fetch-mcp/dist/index.js. Use pwd in your terminal to find the absolute path.

4. Start the Fetch MCP Server

npm start
node dist/index.js

• You should see "Fetch MCP Server running on stdio" or similar output.

Keep this terminal window open while using Claude Desktop.

5. Verify the Connection

• In Claude Desktop, go to MCP settings (under the profile menu).
• Ensure "fetch" appears with a green indicator.
• If not, double-check the path and that the server is running.

You’re now ready to fetch live web content directly in Claude Desktop!

Step 2: Using Fetch MCP Server in Claude Desktop

1. Fetch Web Content

• In Claude Desktop chat, enter:

  Use the fetch tool to get the content from https://example.com.

• Claude will retrieve the page via Fetch MCP and return the text.

• If it fails, verify the server status and the URL.

Note: Claude will always prompt before using MCP tools.

2. Convert Content to Markdown

• Try:

  Fetch https://example.com and convert it to Markdown.

• The server processes the page and returns a clean Markdown version—ideal for documentation or note-taking.

Tip: This is a fast way to convert web articles or documentation for internal knowledge bases.

Step 3: Advanced Fetch MCP Server Features

Take your integration further with these tips:

1. Custom Fetch Parameters

• Example:

  Fetch https://example.com with a max length of 500 characters.

• Useful for summarizing or trimming long pages.

• Additional options (see GitHub for details):

  • ignoreRobotsTxt
  • enableFetchImages for visual content

2. Workflow Automation & Tool Chaining

• Combine with other MCP servers:

  Fetch https://example.com and save the Markdown to Notion.

• Claude can chain actions if multiple servers are configured.

3. Debugging

• Check the absolute path in claude_desktop_config.json.
• For verbose logs, run:

  node dist/index.js --debug
  

• Consult the GitHub issues for troubleshooting.
