Jina AI Remote MCP Server

Remote MCP server providing access to Reader, Embeddings, and Reranker APIs with web/search tools.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "zhijiew-jina-mcp": {
      "url": "https://mcp.jina.ai/sse",
      "headers": {
        "JINA_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

You run a remote MCP server from Jina that gives you access to Reader, Embeddings, and Reranker APIs through convenient MCP endpoints. It’s designed to be easy to connect to from MCP clients, supports both HTTP-based remote access and local stdio proxies, and works with optional API keys for higher rate limits and better performance.

How to use

To connect your MCP-enabled client to the Jina remote MCP server, choose the preferred connection method and configure your client accordingly. You can either use the remote HTTP endpoint or run a local stdio proxy that forwards to the remote MCP server. Both options let you access a suite of tools for web content, search, and embeddings.

Option 1: HTTP remote MCP endpoint (recommended if your client supports direct remote connections). You’ll point your client to the remote SSE URL and optionally provide an API key in the Authorization header.

Option 2: Local stdio proxy (used when your client does not yet support remote MCP servers). You’ll run a local proxy that forwards to the remote MCP SSE URL and passes your API key in the headers.

How to install

Prerequisites: you need Node.js and npm installed on your system. You’ll also need an API key if you want higher rate limits and access to paid features.

Install and run the HTTP remote MCP server config by connecting your client directly to the remote SSE URL.

Security and keys

Some tools require a Jina API key for higher rate limits and broader access. You can obtain a free API key from jina.ai and pass it in the Authorization header as a Bearer token when you configure your MCP client.

Troubleshooting

If you encounter issues with tool calling loops, content truncation, or disconnections, first verify that your API key is valid and that your MCP client supports the chosen connection method. If a client shows a UI error while using a local proxy, try restarting the proxy to refresh tool definitions.

Developer notes

The server exposes a wide set of tools for web content extraction, search, and embeddings. When you integrate, consider using parallel tool variants for faster results and combining URL reads with searches to ensure you get sourced content alongside structured results.
