Milvus MCP Server

Content

Milvus MCP Server is a Zilliz-maintained Model Context Protocol server for Milvus vector database workflows. It gives Claude and other MCP clients access to Milvus collections, text search, vector search, hybrid search, query filters, collection metadata, index operations, inserts, deletes, database switching, and collection load or release operations.

The README documents stdio, SSE, and Streamable HTTP modes. For local Claude or Cursor use, stdio is the safest starting point because the server process stays attached to the MCP client instead of exposing HTTP endpoints.

These sources were reviewed on 2026-06-06. The public Milvus website and docs blocked command-line URL checks, and PyPI metadata for the package name points to a different homepage, so this entry intentionally uses only reachable GitHub source evidence from zilliztech/mcp-server-milvus.

Features

• Zilliz-maintained MCP server for Milvus.
• Stdio, SSE, and Streamable HTTP modes.
• Collection listing and collection information tools.
• Text search, vector search, text-similarity search, multi-vector search, and hybrid search.
• Filtered query operations.
• Collection creation with schema and vector configuration.
• Insert, upsert, bulk insert, and delete-entity operations.
• Index creation and index information tools.
• Collection stats, loading progress, load, and release tools.
• Database listing and database switching.
• Environment-file and command-line configuration for Milvus URI, token, and database.

Installation

Clone the repository and run the server with uv as documented in the README:

git clone https://github.com/zilliztech/mcp-server-milvus.git
cd mcp-server-milvus
uv run src/mcp_server_milvus/server.py --milvus-uri <milvus-uri>

For an MCP client configuration that launches from a checked-out copy:

{
  "mcpServers": {
    "milvus": {
      "command": "uv",
      "args": [
        "--directory",
        "mcp-server-milvus",
        "run",
        "src/mcp_server_milvus/server.py",
        "--milvus-uri",
        "<milvus-uri>"
      ]
    }
  }
}

Review the target URI, token, database, and environment file before starting the server. The README says the environment file takes priority over command-line arguments.

Use Cases

• Ask Claude to list Milvus collections before selecting a retrieval source.
• Inspect collection metadata and stats while debugging ingestion.
• Run vector, text, or hybrid searches with explicit limits and output fields.
• Query collections with filter expressions.
• Create an experimental collection for a local evaluation.
• Insert or upsert curated records after reviewing the target collection and schema.
• Delete entities with a reviewed filter expression.
• Load or release collections while troubleshooting serving state.

Safety and Privacy

Milvus MCP is a database control surface. It can retrieve sensitive indexed content and can also mutate collections, indexes, entities, and database selection. Require human approval for writes, deletes, index creation, database switching, load, and release operations.

Treat vectors and metadata as sensitive even when source text is not returned. Embeddings, IDs, filters, collection names, and retrieval results can reveal private context. Restrict SSE and Streamable HTTP modes to trusted networks and avoid leaking Milvus tokens or query results into prompts, logs, or committed configuration.

Duplicate Check

Existing content includes a general Milvus tools entry in content/tools, but no Milvus MCP Server entry was found in content/mcp. This submission is scoped to zilliztech/mcp-server-milvus, the MCP server, and does not change the existing Milvus database listing.
