What is the Zilliz Cloud MCP Server?
Connect your Zilliz Cloud cluster to any AI agent to automate your vector database operations. This MCP server enables your agent to manage collections, insert data, and perform high-performance similarity searches directly from natural language.
What you can do
- Collection Management — List, describe, create, and drop vector collections in your cluster
- Memory Control — Load and release collections to optimize cluster resource usage and search availability
- Vector Search — Execute complex vector similarity searches (ANN) using customizable metrics and parameters
- Metadata Querying — Query entities using boolean expressions and metadata filters to find specific records
- Data Maintenance — Insert new vector/scalar data and delete entities from your collections
How it works
- Subscribe to this server
- Enter your Zilliz Cluster Endpoint and API Key
- Start managing your vector data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- AI Engineers — Quickly test vector searches and verify collection schemas via natural language
- Data Scientists — Monitor cluster health and data distribution without writing boilerplate code
- Developers — Integrate vector database management and retrieval into your development workflow

Frequently asked questions
How do I find my Cluster Endpoint?
You can find your Cluster Endpoint in the Zilliz Cloud Console under the 'Cluster Details' page. It typically looks like https://in01-xxxxxxxxxxxx.vectordb.zillizcloud.com.
Why do I need to 'load' a collection before searching?
Zilliz requires collections to be loaded into memory to perform high-performance similarity searches. Use the load_collection tool to make your data available for search.
Can I filter my vector search using metadata?
Yes, Zilliz supports hybrid search. You can use the query_entities tool for metadata-only filtering or include filtering expressions in your search_vectors JSON configuration.
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.
