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
`sort_by_relevance`	Rerank documents by relevance to a query via Reranker API	Yes
`deduplicate_strings`	Get top-k semantically unique strings via Embeddings API and submodular optimization	Yes

Optional tools work without an API key but have rate limits. For higher rate limits and better performance, use a Jina API key. You can get a free Jina API key from https://jina.ai

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}"
        ]
    }
  }
}
