Add the Milvus MCP server to Claude Code

Config last verified Jun 1, 2026

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

Prerequisites

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

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.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>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add milvus -- python /path/to/mcp-server-milvus/src/mcp_server_milvus/server.py --milvus-uri http://localhost:19530

3. Restart Claude Code and confirm the Milvus tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
