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 Elasticsearch Vector MCP Server?
The Elasticsearch Vector MCP Server gives AI agents like Claude, ChatGPT, and Cursor direct access to Elasticsearch Vector via 6 tools. Empower vector search via Elasticsearch — perform dense vector kNN searches, handle index mappings, and index embedding documents directly from any AI agent. 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 Elasticsearch Vector
Ask your AI agent "Perform a kNN search in index 'product-embeddings' with vector [0.1, 0.2, ...]" and get the answer without opening a single dashboard. With 6 tools connected to real Elasticsearch Vector 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.

What the Elasticsearch Vector MCP Server unlocks
Connect your Elasticsearch cluster to any AI agent and take full control of your vector search and semantic discovery workflows through natural conversation.
What you can do
- AI-Powered Vector Search — Perform raw K-Nearest Neighbors (kNN) computations mapping absolute semantic similarity across multi-dimensional embedding arrays
- Index Orchestration — Enumerate active storage namespaces and validate physical Elasticsearch clusters tracking explicit dimensional shards securely
- Schema Management — Analyze specific index mapping rules and provision strictly typed data structures enforcing numeric dimensions for cluster readiness
- Document Indexing — Command synchronous bulk insertions attaching exact
dense_vectorembedding payloads to persist data into raw Lucene partitions - Data Invalidation — Enforce immediate hard document vaporization finding specific exact UUIDs stripping records from physical indices seamlessly
- Metadata Auditing — Analyze dimensional constraints and matching similarity thresholds perfectly to verify your vector search configurations
How it works
1. Subscribe to this server
2. Enter your Elasticsearch Host URL and API Key (found in Kibana > Stack Management > Security > API Keys)
3. Start managing your vector search from Claude, Cursor, or any MCP-compatible client
Who is this for?
- AI Engineers — perform semantic searches and test embedding models without writing complex query DSL
- Software Developers — index embedding documents and verify kNN search results directly from the IDE or chat
- Data Scientists — monitor vector index mappings and verify dimensional constraints using natural language
- Ops Teams — verify cluster index health and manage vector storage namespaces in real-time
Frequently asked questions about the Elasticsearch Vector MCP Server
Can my agent perform kNN searches using raw vector arrays?
Yes. Use the 'search' tool. Provide the index name and a JSON array representing your query vector. The agent will perform raw K-Nearest Neighbors computations to find the most semantically similar documents.
How do I create a new vector index with specific dimensions via chat?
Use the 'create_index' tool. You can specify the index name and the number of dimensions (e.g., 1536 for OpenAI embeddings). The agent will provision the strictly typed data structure in your Elasticsearch cluster.
Can I delete a single document from a vector index through the agent?
Absolutely. Use the 'delete_document' tool with the index and document ID. The agent will enforce immediate document vaporization, stripping the record from the physical Lucene partitions.
