Use the Modelglass MCP in Claude Code

The Modelglass MCP connects Claude Code directly to live AI model pricing and capability data — image generation, language models, and video generation. Ask natural questions about model costs, compare providers, and get routing recommendations, all from inside your Claude Code session.

Add to Claude Code

Add the mcpServers block to your ~/.claude/settings.json (or a project-level .mcp.json for project-scoped access):

{
  "mcpServers": {
    "modelglass": {
      "type": "http",
      "url": "https://modelglass-api.vercel.app/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_KEY_HERE"
      }
    }
  }
}

Or via the Claude Code CLI:

claude mcp add --transport http modelglass https://modelglass-api.vercel.app/mcp --header "Authorization: Bearer YOUR_KEY_HERE"

After saving, restart Claude Code to load the new server. Run /mcp to confirm the modelglass server shows as connected.

Keys don't expire

Your API key is persistent — it works across sessions and Claude Code restarts without needing to be refreshed. If a key stops working (e.g. after regeneration), update the Authorization header in your settings and restart Claude Code.

Troubleshooting

Connection shows "Failed to connect"

Check that your key is valid: run curl -s https://modelglass-api.vercel.app/v1/health -H "Authorization: Bearer YOUR_KEY". A 200 response confirms the key works. If you get 401, regenerate your key at modelglass.com.au/account →

Claude Code shows the server but tools aren't available

Run /mcp in Claude Code to reconnect. If the server shows ✘ Failed to connect, confirm the type: "http" field is present in your config (not type: "url" — that is a different transport).
