Claude Code

Terminal
claude mcp add -s user --transport http jina https://mcp.jina.ai/v1 --header "Authorization: Bearer ${JINA_API_KEY}"

Any client that supports remote servers

Config
{"mcpServers": {"jina-mcp-server": {"url": "https://mcp.jina.ai/v1", "headers": {"Authorization": "Bearer ${JINA_API_KEY}"}}}}

Codex, in ~/.codex/config.toml

Terminal
[mcp_servers.jina-mcp-server]
command = "npx"
args = ["-y", "mcp-remote", "https://mcp.jina.ai/v1", "--header", "Authorization: Bearer ${JINA_API_KEY}"]

Load only the search and read tools

Terminal
https://mcp.jina.ai/v1?include_tags=search,read

Some clients do not expand ${JINA_API_KEY}; then paste the real key (it starts with jina_). Clients without remote server support connect through the mcp-remote proxy, as in the Codex example.

Or paste this into your coding agent: Connect the Jina AI MCP server to my coding agent using its documented setup: https://github.com/jina-ai/MCP.

What the Jina AI MCP server does

The Jina AI MCP server is a hosted server that connects an AI agent to four Jina APIs. The best-known tool reads a web page or PDF through Jina Reader and returns it as Markdown, or returns only the passages that answer a question you pass in. Other tools capture a screenshot of a page and estimate when a page was published or last updated.

Jina's search tools cover the open web, web images, arXiv preprints and SSRN papers, which makes the server useful for academic lookups as well as general ones. A PDF tool pulls figures, tables and equations out of papers. Two ranking tools use Jina's Reranker and Embeddings models to sort documents by relevance to a query and to drop near-duplicate strings.

The server runs at mcp.jina.ai and has no local install. You can cut the tool list down with query parameters on the URL, such as include_tags=search,read, which saves context tokens in the agent. Jina AI is now part of Elastic, and the GitHub repo had 869 stars on 2026-10-01.

Tools it gives your agent

  • primer
  • read_url
  • capture_screenshot_url
  • guess_datetime_url
  • search_web
  • search_arxiv
  • search_ssrn
  • search_images
  • search_jina_blog
  • sort_by_relevance
  • deduplicate_strings
  • extract_pdf

When to use Jina AI

  • Your agent needs a web page or PDF as clean Markdown, quickly and with no setup.
  • You want to search arXiv or SSRN papers from inside an agent.
  • You have a long list of search hits and want them reranked by relevance before reading.
  • You need to know roughly when a page was published.

When to pick something else

  • Search without signing up: search_web, search_arxiv and the ranking tools need a Jina API key, and without one page reading runs at a lower rate limit.

What Jina AI needs

  • A Jina API key for search, reranking and PDF extraction (reading works without one, at a lower rate limit)

What the Jina AI MCP server costs

Free and open source under Apache-2.0; reading pages works without a key at a rate limit, new API keys come with free tokens, and use past that is billed by token.

  • Apify: The Apify MCP server gives AI agents thousands of ready-made scrapers and automation tools from Apify Store, such as Google Maps, Instagram and search result scrapers, which the agent can find and run on demand.
  • Brave Search: The Brave Search MCP server gives AI agents Brave's independent search index: web, news, image, video, local and place search, plus pre-extracted page text for grounding and AI summaries.
  • Exa: The Exa MCP server gives AI agents web search and page reading through Exa's search engine, plus optional advanced filters and Exa Agent runs for multi-step research with structured output.
  • Firecrawl: The Firecrawl MCP server gives AI agents live web access through Firecrawl: search the web, scrape a URL into Markdown or JSON, map and crawl whole sites, and click through pages.
