EV Life Content MCP Server

This MCP (Model Context Protocol) server provides content querying tools for electricvehicle.life. It offers two deployment options: a local stdio-based server for direct Claude Desktop integration, and a Cloudflare Workers deployment for remote access.

Available Tools

The MCP server provides four content querying tools:

1. search_content - Search for specific terms in electricvehicle.life content with context
2. get_section - Retrieve specific sections by title/heading
3. get_full_content - Get the complete content with optional truncation
4. get_content_summary - Generate content statistics and table of contents

Quick Start

Option 1: Local Stdio Server (Recommended)

1. Clone and install dependencies:

git clone <your-repo-url>
cd evlife-mcp-server
npm install

2. Configure Claude Desktop by adding to your MCP config:

{
  "mcpServers": {
    "evlife-content": {
      "command": "node",
      "args": ["/path/to/evlife-mcp-server/mcp-stdio.js"],
      "env": {}
    }
  }
}

3. Restart Claude Desktop and the tools will be available.

Option 2: Cloudflare Workers Deployment

1. Prerequisites:

   • Sign up for a Cloudflare account
   • Install Wrangler CLI

2. Authenticate with Cloudflare:

npx wrangler login

3. Deploy to Cloudflare Workers:

npm run deploy

This will deploy your MCP server to a URL like: evlife-mcp-server.<your-account>.workers.dev/sse

4. One-Click Deploy (Alternative):

   

Cloudflare Workers Features

This MCP server leverages several Cloudflare Workers features:

• Edge Computing: Runs close to users worldwide for low latency
• Durable Objects: Maintains stateful MCP agent instances
• Server-Sent Events: Real-time communication with MCP clients
• No Cold Starts: Fast response times with Cloudflare's V8 isolates
• Built-in Observability: Monitoring and analytics through Cloudflare dashboard

Worker Configuration

The server exposes two endpoints:

• /sse - Server-Sent Events endpoint for MCP communication
• /mcp - Standard MCP endpoint

Configuration is managed in wrangler.jsonc:

{
  "name": "evlife-mcp-server",
  "main": "src/index.ts",
  "compatibility_date": "2025-03-10",
  "durable_objects": {
    "bindings": [
      {
        "class_name": "MyMCP",
        "name": "MCP_OBJECT"
      }
    ]
  }
}

Development

Local Development with Wrangler

# Start the Cloudflare Workers dev server
npm run dev

# Run TypeScript type checking
npm run type-check

# Format code
npm run format

# Fix linting issues
npm run lint:fix

Local Development with Stdio Server

# Test the stdio server directly
node mcp-stdio.js

# The server will wait for MCP protocol messages on stdin

Content Source

The server fetches content from https://electricvehicle.life/llms-full.txt and caches it for 5 minutes to improve performance. The content includes:

• Personal blog posts and essays
• Technical documentation
• Project descriptions
• Conference notes and insights

Test locally with MCP Inspector

npx @modelcontextprotocol/inspector

Connecting to Claude Desktop

For Local Stdio Server

Add this to your Claude Desktop MCP configuration:

{
  "mcpServers": {
    "evlife-content": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-stdio.js"],
      "env": {}
    }
  }
}

For Deployed Workers (with mcp-remote)

{
  "mcpServers": {
    "evlife-content": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://your-worker-url.workers.dev/sse"
      ]
    }
  }
}

Connect to Cloudflare AI Playground

For deployed Workers, you can test the MCP server using Cloudflare AI Playground:

1. Go to https://playground.ai.cloudflare.com/
2. Enter your deployed MCP server URL (your-worker-url.workers.dev/sse)
3. Test the content querying tools directly

Deployment Customization

Custom Domain (Optional)

To use a custom domain with your Cloudflare Worker:

1. Add a custom domain in your Cloudflare dashboard
2. Update wrangler.jsonc with your domain:

{
  "routes": [
    {
      "pattern": "mcp.yourdomain.com/*",
      "custom_domain": true
    }
  ]
}

Environment Variables

Add environment variables for configuration:

# Set environment variables
npx wrangler secret put API_KEY
npx wrangler secret put CONTENT_URL

Then access them in your Worker:

// In src/index.ts
const contentUrl = env.CONTENT_URL || "https://electricvehicle.life/llms-full.txt";

Troubleshooting

Common Issues

1. MCP Connection Failed

   • Ensure the server URL is correct
   • Check that the Worker is deployed and accessible
   • Verify Claude Desktop configuration

2. Content Fetching Errors

   • Check if https://electricvehicle.life/llms-full.txt is accessible
   • Verify network connectivity from the Worker
   • Monitor Cloudflare logs for fetch errors

3. Development Server Issues

   • Run npm install to ensure dependencies are installed
   • Check Node.js version compatibility (v18+ recommended)
   • Use npm run type-check to identify TypeScript errors

Monitoring

• View Worker logs in the Cloudflare dashboard
• Use wrangler tail for real-time log monitoring
• Monitor MCP server logs in Claude Desktop

Customization

To add your own tools:

• Stdio server: Edit mcp-stdio.js and add new tool handlers
• Workers server: Edit src/index.ts and add tools in the init() method

Example: Adding a New Tool

// In src/index.ts or mcp-stdio.js
this.server.tool(
    "new_tool",
    {
        parameter: z.string().describe("Tool parameter")
    },
    async ({ parameter }) => {
        // Tool implementation
        return {
            content: [{ type: "text", text: `Result: ${parameter}` }]
        };
    }
);
