[See setup guidance ↓](#setup)[Original source ↗](https://github.com/jina-ai/MCP) SOURCE REVIEW Reviewed 2026-10-13 Evidence 3 linked sources Publisher Jina AI Licence [Apache-2.0 ↗](https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/LICENSE) Revision 5d6eb191a75d [Read what was—and wasn’t—checked ↓](#review) “A remote Model Context Protocol (MCP) server for the Jina Reader, Search, Embeddings and Reranker APIs” [Jina AI · upstream description ↗](https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/README.md) Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Published in Jina AI's own repository; the README at this commit documents the hosted endpoint https://mcp.jina.ai/v1 and a table of 12 tools that marks which need a Jina API key. - The README documents server-side filtering (include_tools, exclude_tools, include_tags, exclude_tags, max_tokens) applied before tool registration, so a client loads only the tool schemas it asks for. ### A good fit for - Reading web pages and PDFs as markdown, searching arXiv or SSRN, and reranking passages from an MCP client - Pulling only the passages of a long page that answer a question, using read_url with question, topk and chunk_size ### Weigh up before choosing - The README lists reproduced failure modes of read_url with a question: positional questions fail, tables and fenced code are removed before ranking, inline code loses tokens, and login walls come back as content without an error. - This repository is the Cloudflare Workers source of the hosted service; the running endpoint was not compared against this commit. The README says v1.10.0 removed a show_api_key tool because it returned the bearer token into the conversation. - The README says OCR on read_url bills more tokens per page than a plain read. No call was made to the endpoint. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - README.md at 5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa - LICENSE at the same commit - package.json at the same commit ### Our findings - The README says the older /sse endpoint is kept for backward compatibility and that /sse and /v1 both use Streamable HTTP, not the deprecated SSE transport. - The README's first configuration block marks the Authorization header optional with an inline comment; the example here is that block without the comment, which is not valid JSON. - read_url arrays cap at 5 entries; a read with a question gets a 60-second budget against 30 seconds for a plain read. ### Not established by this review - Any call to https://mcp.jina.ai/v1 - Tool filtering parameters - Local wrangler deployment The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. [Upstream setup instructions ↗](https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/README.md) - Nothing is installed for the hosted server. Add https://mcp.jina.ai/v1 as a remote HTTP server, with an Authorization bearer header carrying a Jina API key when the tools need one. The README's Claude Code command spans two lines and is not reproduced here. - Clients without remote support use the mcp-remote proxy shown in the README. Do not commit the key. ### Before you start - A Jina API key for search, rerank, deduplication and PDF extraction tools ### Documented configuration example Use the client and authentication context described in the setup guidance. Configuration formats vary between hosts. { "mcpServers": { "jina-mcp-server": { "url": "https://mcp.jina.ai/v1", "headers": { "Authorization": "Bearer ${JINA_API_KEY}" } } } } Copy configuration ↗ ### Compatibility Claude Code · Codex · Claude Desktop · Cursor · Windsurf · LM Studio ### Implementation TypeScript ### Transports Streamable HTTP ### Hosted Jina endpoint, optional API key - Fetches public web pages, PDFs and screenshots through Jina's Reader API - Sends documents and queries to Jina's embeddings and reranker APIs ### Cost model Apache-2.0 source. Jina API usage is metered by Jina; the README says some tools work without a key at rate limits. No rate was reviewed. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource. Check upstream before adopting a new version. - [Jina AI MCP README ↗](https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/README.md) Checked 2026-10-13 https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/README.md Supports: Hosted endpoint, Tool table and key requirements, Tool filtering, Removed tools, Failure modes - [Jina AI MCP LICENSE ↗](https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/LICENSE) Checked 2026-10-13 https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/LICENSE Supports: Apache License 2.0 - [Jina AI MCP package.json ↗](https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/package.json) Checked 2026-10-13 https://github.com/jina-ai/MCP/blob/5d6eb191a75d8e67b6e01ce427f0cc5c05c800aa/package.json Supports: Cloudflare Workers project jina-mcp 1.10.0 KEEP COMPARING ## Other approaches to consider.
