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, video generation, and audio. Ask natural questions about model costs, compare providers, and get routing recommendations, all from inside your Claude Code session.

Add to Claude Code

Claude Code only (CLI and IDE extensions). Claude Desktop uses an OAuth-based connector that requires a different transport — Bearer-token MCP servers like this one are not compatible with it yet. Desktop support is planned once OAuth is implemented.

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).

Example questions

Once connected, try asking Claude Code:

› What's the cheapest model for image generation right now?
› Compare FLUX.1 [dev] and DALL-E 3 across all capability dimensions
› Which models are rated Strong for text rendering?
› What would 10,000 generations per month cost across all tracked models?
› Which providers offer per-megapixel pricing?
› Compare GPT-4o mini vs Claude 3.5 Haiku on cost and capability
› Which LLMs are strongest for coding at under $2 per million tokens?
› What's the price difference between DeepSeek R1 and o4-mini for reasoning tasks?
› Compare Kling 1.6 and Runway Gen-4 for video generation cost
› Which video models support the longest clip duration?
› What plan tier is my API key on, and how many requests do I have left today?
› Which models are FLUX.1 [pro]'s closest competitors on price?

What the MCP can access

The Modelglass MCP exposes seven tools:

Tool	What it does
modelglass_list_models	browse and filter all tracked models with current pricing
modelglass_get_model	full profile for a specific model including capability ratings
modelglass_compare_models	side-by-side comparison with routing recommendations
modelglass_get_pricing_feed	structured pricing feed for all active tiers
modelglass_route_task	recommend the best current-generation LLM for a coding task category
modelglass_get_account	the calling key's own plan tier and key status
modelglass_get_competitors	a model's closest competitors with live pricing and price-delta ratio (retired ones show a labelled last price)

Data is updated daily by automated agents monitoring provider pricing pages.

Plan limits
