Add the Milvus MCP server to Claude Desktop

Config last verified Jun 1, 2026

The exact config to run Milvus in Claude Desktop — paste it in, restart, and the tools load.

Prerequisites

Claude Desktop installed.

On Windows the file lives at %APPDATA%\Claude\claude_desktop_config.json.

2. Add this configuration

Add to ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "milvus": {
      "command": "python",
      "args": [
        "/path/to/mcp-server-milvus/src/mcp_server_milvus/server.py",
        "--milvus-uri",
        "http://localhost:19530"
      ],
      "env": {
        "MILVUS_URI": "<MILVUS_URI>",

  }

Gotchas

Claude Desktop reads MCP servers from an "mcpServers" object, but the config file is stdio-only: it cannot dial a remote URL directly. To reach a remote server you bridge it locally by running "npx mcp-remote <url>" as the command. Native remote Connectors exist on paid plans, but not through this config file, so the bridge is the portable path.
