Add the Argo CD MCP server to Claude Code

Config last verified Jun 1, 2026

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

Prerequisites

Claude Code installed.
ARGOCD_BASE_URL — Base URL of your Argo CD instance (e.g. https://argocd.example.com).
ARGOCD_API_TOKEN — Argo CD API token used to authenticate API calls.

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.json

json

{
  "mcpServers": {
    "argocd": {
      "command": "npx",
      "args": [
        "-y",
        "argocd-mcp@latest",
        "stdio"
      ],
      "env": {
        "ARGOCD_BASE_URL": "<ARGOCD_BASE_URL>",
        "ARGOCD_API_TOKEN": "<ARGOCD_API_TOKEN>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add argocd -- npx -y argocd-mcp@latest stdio

3. Restart Claude Code and confirm the Argo CD 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.
