MCP Server

Using stdio Transport (Default)

For local integrations spawned by another process (e.g., Claude Desktop, VS Code, Cursor):

{
  "mcpServers": {
    "jina-mcp-tools": {
      "command": "npx",
      "args": [
        "jina-mcp-tools",
        "--transport", "stdio",
        "--tokens-per-page", "15000",
        "--search-endpoint", "standard"
      ],
      "env": {
        "JINA_API_KEY": "your_jina_api_key_here_optional"
      }
    }
  }
}

Using HTTP Transport

For remote server deployments accessible via HTTP:

Start the server:

# With API key
JINA_API_KEY=your_api_key npx jina-mcp-tools --transport http --port 3000

# Without API key (reader tool only)
npx jina-mcp-tools --transport http --port 3000

Connect from MCP clients:

• MCP Inspector: npx @modelcontextprotocol/inspector → http://localhost:3000/mcp

• Claude Code: claude mcp add --transport http jina-tools http://localhost:3000/mcp

• VS Code: code --add-mcp '{"name":"jina-tools","type":"http","url":"http://localhost:3000/mcp"}'

CLI Options:

• --transport - Transport type: stdio or http (default: stdio)

• --port - HTTP server port (default: 3000, only for HTTP transport)

• --tokens-per-page - Tokens per page for pagination (default: 15000)
