What is the Elasticsearch Vector MCP Server?
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
- Subscribe to this server
- Enter your Elasticsearch Host URL and API Key (found in Kibana > Stack Management > Security > API Keys)
- 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
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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
