What is ArchitectGBT?

Choosing the right AI model shouldn't take hours of research. ArchitectGBT analyzes your project requirements and recommends the best model with actual cost estimates, not marketing fluff.

Instead of manually comparing pricing tables across OpenAI, Anthropic, Google, Meta, and Mistral, you get:

• AI-powered recommendations based on your project requirements

• Cost optimization with realistic usage estimates

• Model comparison across 50+ models with real-time pricing

• Production-ready code in TypeScript and Python

• Direct IDE integration via Model Context Protocol (MCP)

This MCP server brings ArchitectGBT's intelligence directly into your IDE, so you never have to leave your coding flow.

Why This vs Cursor's Auto?

Cursor's Auto feature is great for quick model switching, but it doesn't solve the research problem:

ArchitectGBT solves:

1. Cost planning - Get realistic estimates before you build, not surprise bills after

2. Model discovery - Find models you didn't know existed (Mistral, Cohere, specialized models)

3. Requirements matching - Match your specific use case (context window needs, latency requirements, budget constraints)

4. Production templates - Get working integration code, not just model names

When to use Cursor Auto: Switching between models you already know When to use ArchitectGBT: Figuring out which model to use in the first place

Think of it as research before execution. ArchitectGBT helps you make the decision, Cursor Auto helps you execute it.

2. Verify Pro status — API keys only work for Pro subscribers → Check subscription

3. Regenerate key — Create a new key at Settings

4. Check config — Ensure key is in env section of your MCP config

5. Restart IDE — Changes require full restart

Example config:

{
  "mcpServers": {
    "architectgbt": {
      "command": "npx",
      "args": ["-y", "architectgbt-mcp@latest"],
      "env": {
        "ARCHITECTGBT_API_KEY": "agbt_abc123xyz..."
      }
    }
  }
}

MCP Server Not Loading

Problem: Tools aren't showing up in your IDE.

Solutions:

1. Check Node.js — Requires Node.js >= 18.0.0 (node --version)

2. Verify config — Check JSON syntax in your MCP config file

3. Restart IDE — Full restart required after config changes

4. Test manually — Run npx -y architectgbt-mcp@latest in terminal

5. Check network — Verify you can access https://architectgbt.com/api/models

For Cursor users: Look for the connection icon in the bottom right corner

Models Not Showing

Problem: list_models returns empty or errors.

Solutions:

1. Remove API key — Free tier doesn't need env section at all

2. Use basic config:

   {
     "mcpServers": {
       "architectgbt": {
         "command": "npx",
         "args": ["-y", "architectgbt-mcp@latest"]
       }
     }
