The TierZero plugin for Claude Code wraps the MCP server with a /tierzero slash command and a skill that auto-loads when production context would help. Authentication is OAuth — there’s nothing to copy or paste.

​
Install

  1. Add the TierZero marketplace:
/plugin marketplace add TierZeroAI/tierzero-claude-code
  1. Install the plugin:
/plugin install tierzero@tierzero
  1. Run any /tierzero command. The first time, Claude Code prompts you to authenticate — run /mcp and approve the connection in your browser.
/tierzero What errors occurred in payment-service in the last hour?

​
Project-wide installation

To enable the TierZero plugin for your whole team, add this to your project’s .claude/settings.json and commit it: 
{
  "extraKnownMarketplaces": {
    "tierzero": {
      "source": {
        "source": "github",
        "repo": "TierZeroAI/tierzero-claude-code"
      }
    }
  },
  "enabledPlugins": {
    "tierzero@tierzero": true
  }
}
Anyone who clones the project will have the plugin available; each user authenticates individually on first use.

​
Usage

With the plugin installed, Claude Code automatically loads the tierzero skill when your task would benefit from production context — it can query TierZero in the background while it continues working on your code. You can also explicitly start an investigation: 
/tierzero What errors occurred in payment-service in the last hour?
Or pull existing context from a TierZero chat or investigation: 
/tierzero:fetch-context https://app.tierzero.ai/chat/c/<GlobalID>
