How to Set Up and Use Jina AI
The Jina AI Remote MCP Server is a hosted, streamable-HTTP MCP endpoint that gives AI assistants access to Jina's suite of 19+ web intelligence tools, including web search, URL content extraction, ArXiv and SSRN academic search, image search, semantic reranking, text classification, and query expansion. It connects directly to Jina's cloud APIs at mcp.jina.ai, so no local server process is needed. Developers and researchers use it to give Claude the ability to read live web content, find academic papers, and perform semantic analysis without writing custom integrations.
Prerequisites
- A Jina AI API key (free tier available at jina.ai)
- An MCP client that supports HTTP/SSE transport (Claude Code, Cursor, or any MCP 2025-03-26 client)
- Node.js 18+ installed if using mcp-remote as a proxy for clients without native HTTP MCP support
- No local server installation required — the server runs on Jina's infrastructure
Obtain a Jina API key
Visit jina.ai to sign up and generate a free API key. Some tools work without a key but rate limits are very low.
Add the server to Claude Code (native HTTP support)
Claude Code supports remote MCP servers natively. Use this one-line command to add the Jina server at the user scope.
claude mcp add -s user --transport http jina https://mcp.jina.ai/v1 \
--header "Authorization: Bearer ${JINA_API_KEY}"Configure for clients without native HTTP transport
For Claude Desktop or other clients that only support stdio, use the mcp-remote proxy package to bridge to the HTTP endpoint.
{
"mcpServers": {
"jina": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.jina.ai/v1",
"--header",
"Authorization: Bearer ${JINA_API_KEY}"
],
"env": {
"JINA_API_KEY": "your-jina-api-key"
}
}
}
}Filter tools to reduce context token usage (optional)
The server exposes 19+ tools by default. Use URL query parameters to include only the tools you need, saving Claude's context window.
# Include only search and read tools:
https://mcp.jina.ai/v1?include_tags=search,read
# Exclude parallel variants:
https://mcp.jina.ai/v1?exclude_tags=parallelRestart your MCP client and test
Restart Claude Code or Claude Desktop. Ask Claude to read a URL or search the web to verify the Jina tools are available.
Jina AI Examples
Client configuration
Claude Desktop configuration using mcp-remote as a proxy to the Jina AI HTTP endpoint.
{
"mcpServers": {
"jina": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.jina.ai/v1",
"--header",
"Authorization: Bearer ${JINA_API_KEY}"
],
"env": {
"JINA_API_KEY": "your-jina-api-key"
}
}
}
}Prompts to try
Once configured, use these prompts to leverage Jina's web intelligence tools through Claude:
- "Read the content at https://example.com/article and summarize the key points"
- "Search the web for the latest research on transformer attention mechanisms"
- "Find recent ArXiv papers on retrieval-augmented generation and list the top 5"
- "Rerank these 10 search results by relevance to my query about vector databases"
- "Extract and classify the text from this PDF URL: https://arxiv.org/pdf/2310.01848"Troubleshooting Jina AI
401 Unauthorized errors when calling Jina tools
Verify JINA_API_KEY is set correctly in your environment or MCP config env block. The API key must be passed as a Bearer token in the Authorization header. Generate a new key at jina.ai if needed.
Claude Desktop does not recognize the remote MCP server
Claude Desktop does not natively support HTTP MCP transport. Use the mcp-remote proxy approach: set command to 'npx' and args to ['mcp-remote', 'https://mcp.jina.ai/v1', '--header', 'Authorization: Bearer YOUR_KEY'].
Context window fills up quickly with too many Jina tools
Use URL filtering to reduce the tool count. Append '?include_tags=search,read' to the endpoint URL to expose only the tools you need, or use '?exclude_tags=parallel' to remove the parallel variants.
