Vinkius supports streamable HTTP and SSE.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
What is the Jina AI MCP Server?
The Jina AI MCP Server gives AI agents like Claude, ChatGPT, and Cursor direct access to Jina AI via 6 tools. Power your RAG and search via Jina AI — generate embeddings, rerank documents, read URLs, and perform semantic web search. Powered by the Vinkius - no API keys, no infrastructure, connect in under 2 minutes.
Built-in capabilities (6)
Tools for your AI Agents to operate Jina AI
Ask your AI agent "Extract the main content from 'https://jina.ai/embeddings' as Markdown" and get the answer without opening a single dashboard. With 6 tools connected to real Jina AI data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
Why teams choose Vinkius
One subscription gives you access to thousands of MCP servers - and you can deploy your own to the Vinkius Edge. Your AI agents only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure and security, zero maintenance.

Jina AI (Search Foundation & LLM Grounding) MCP Server capabilities
6 toolsPerform zero-shot text classification
The input must be a JSON array of strings. Generate vector embeddings from text
Excellent for grounding LLMs with live web content. Read and extract clean text from a URL
Rerank search documents against a query
Returns context-rich structured search results, suitable for RAG pipelines. Perform a semantic web search
Semantically segment and chunk long text content
What the Jina AI (Search Foundation & LLM Grounding) MCP Server unlocks
Connect your Jina AI account to any AI agent and take full control of state-of-the-art search infrastructure and LLM grounding through natural conversation.
What you can do
- LLM Grounding & Reader — Extract clean, readable Markdown context from any web URL, stripping away noise and navigation to feed high-quality data to your agent
- Semantic Web Search — Perform context-rich web searches that return structured results specifically optimized for RAG pipelines and AI analysis
- Vector Embeddings — Generate high-quality embeddings using Jina's advanced models to power semantic search and document similarity workflows
- Precision Reranking — Improve search relevance by re-ordering candidate documents based on their semantic match to a specific query block
- Zero-Shot Classification — Categorize text inputs against custom labels with confidence scores without training specific models manually
- Intelligent Segmentation — Break down long documents into semantically cohesive chunks to optimize retrieval-augmented generation (RAG)

Frequently asked questions about the Jina AI (Search Foundation & LLM Grounding) MCP Server
How can Jina AI help my agent provide more accurate answers?
Use the read_url_content tool to give your agent access to live web data. By converting URLs into clean Markdown, your agent can 'read' the latest information from documentation or news sites, grounding its answers in up-to-date facts.
What is the difference between search and rerank?
Search (embeddings) helps you find a broad set of relevant documents quickly. Rerank takes that smaller set and uses a more powerful cross-encoder model to sort them by exact semantic matching, ensuring the absolute best context is sent to the LLM.
Can I search the web through my agent using Jina?
Absolutely. Use the search_web_jina tool to dispatch a semantic query. Your agent will return structured results including snippets and titles from top web pages, allowing it to synthesize answers from the live internet.
