Add the Milvus MCP server to Windsurf

Config last verified Jun 1, 2026

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

Prerequisites

Windsurf installed.
MILVUS_URI — URI of the Milvus instance (e.g. http://localhost:19530 or a Zilliz Cloud endpoint).

Setup

1. Open `~/.codeium/windsurf/mcp_config.json`

On Windows the file lives at %USERPROFILE%\.codeium\windsurf\mcp_config.json.

2. Add this configuration

Add to ~/.codeium/windsurf/mcp_config.json

~/.codeium/windsurf/mcp_config.json

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>",
        "MILVUS_TOKEN": "<MILVUS_TOKEN>"
      }
    }
  }
}

3. Restart Windsurf and confirm the Milvus tools load.

Gotchas

Windsurf's Cascade reads MCP servers from an "mcpServers" object in ~/.codeium/windsurf/mcp_config.json. Unlike most clients, remote servers are configured with the "serverUrl" field rather than "url", so a config that uses "url" silently fails to connect. Native remote transport is supported without an OAuth flow.
