What is the ClickHouse (Vector Search) MCP Server?
Connect your ClickHouse cluster to any AI agent and take full control of your analytical and vector data through natural conversation.
What you can do
- Schema Management — List databases and tables, and inspect deep column schemas including specialized Array(Float32) vector types
- SQL Execution — Push arbitrary DML, DDL, or SELECT queries to your cluster to manage data and generate real-time reports
- Vector Search — Identify mathematical distance traces using cosineDistance or L2Distance metrics for high-dimensional semantic search
- Cluster Monitoring — Extract internal structural states, row counts, and compression ratios to audit cluster health
- Capability Auditing — Check instance versions and binary limits to identify exact capability branches like HNSW support
How it works
- Subscribe to this server
- Enter your ClickHouse URL (Cloud or self-hosted), Username, and Password
- Start querying your analytical data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Data Analysts — generate complex analytical reports and execute SQL queries using natural language
- AI Developers — test and debug vector similarity searches and semantic matching without writing boilerplate code
- Database Administrators — monitor table statistics, compression ratios, and cluster versions across environments
- Product Teams — quickly verify analytical data and vector distributions during the prototyping phase
Built-in capabilities (7)

Frequently asked questions
Can my agent perform high-speed vector similarity searches?
Yes. Provide the database, table, and the vector embedding array in JSON format. The agent uses ClickHouse's native distance functions (cosine or L2) to return the closest matches, leveraging ClickHouse's industry-leading OLAP performance.
Can I execute arbitrary SQL commands directly through the agent?
Absolutely. The 'execute_sql' tool allows you to push any valid ClickHouse SQL (DML, DDL, or SELECT) to your cluster. This is perfect for managing tables, updating records, or generating custom analytical reports on the fly.
How do I check if my ClickHouse instance supports HNSW indices?
Ask your agent to get the version details. The agent checks your ClickHouse build and identifies exactly which capability branches are active, confirming if advanced vector features like HNSW support are available in your runtime environment.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query ClickHouse (Vector Search) tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
