## How to Use MCPs in Development

### In Phase Planning
When creating `/gsd:plan-phase N`:
- Researchers can use Hugging Face tools to discover libraries and models
- Use WebSearch for current best practices
- Query papers for architectural patterns

### In Phase Execution
When running `/gsd:execute-phase N`:
- Download models from Hugging Face
- Use WebFetch for documentation
- Run Spaces for prototyping UI patterns

## Configuration

Add to `.planning/config.json` to enable MCP usage:

```json
{
  "mcp": {
    "huggingface": {
      "enabled": true,
      "authenticated_user": "mystiatech",
      "default_result_limit": 10
    },
    "web_search": {
      "enabled": true,
      "domain_restrictions": []
    },
    "code_tools": {
      "enabled": true
    }
  }
}
```

## Research Output Format

When researchers use MCPs, they produce:
- `.planning/research/STACK.md` — Technologies and libraries
- `.planning/research/FEATURES.md` — Capabilities and patterns
- `.planning/research/ARCHITECTURE.md` — System design patterns
- `.planning/research/PITFALLS.md` — Common mistakes and solutions

These inform phase planning and implementation.
