Jina AI Remote MCP Server

A remote Model Context Protocol (MCP) server that provides access to Jina Reader, Embeddings and Reranker APIs with a suite of URL-to-markdown, web search, image search, and embeddings/reranker tools:

Tool	Description	Is Jina API Key Required?
read_url	Extract clean, structured content from web pages as markdown via Reader API	Optional*
capture_screenshot_url	Capture high-quality screenshots of web pages via Reader API	Optional*
search_web	Search the entire web for current information and news via Reader API	Yes
search_arxiv	Search academic papers and preprints on arXiv repository via Reader API	Yes
search_image	Search for images across the web (similar to Google Images) via Reader API	Yes

Usage

For client that supports remote MCP server:

{
  "mcpServers": {
    "jina-mcp-server": {
      "url": "https://mcp.jina.ai/sse",
      "headers": {
        "Authorization": "Bearer ${JINA_API_KEY}" // optional
      }
    }
  }
}

For client that does not support remote MCP server yet, you need mcp-remote a local proxy to connect to the remote MCP server.

{
  "mcpServers": {
    "jina-mcp-server": {
      "command": "npx",
      "args": [
        "mcp-remote", 
        "https://mcp.jina.ai/sse"
        // optional bearer token
        "--header",
        "Authorization: Bearer ${JINA_API_KEY}"
        ]
    }
  }
}
