Your MCP server will be live at:

https://jina-mcp-server.<your-subdomain>.workers.dev/mcp

4. Connect from an MCP client

Add the server URL to any MCP-compatible client (Claude Desktop, Cursor, Windsurf, AI Playground, MCP Inspector, etc.):

{
  "mcpServers": {
    "jina": {
      "url": "https://jina-mcp-server.<your-subdomain>.workers.dev/mcp"
    }
  }
}

Local development

echo 'JINA_API_KEY=your_key_here' > .dev.vars
npm run dev

The server will be available at http://localhost:8787/mcp.
