# MCP-Powered Development

> **Named `/mcp-guide` (not `/mcp`)** to avoid colliding with Claude Code's built-in `/mcp` command (the MCP server manager). This is a reference for which MCP toolset to reach for and when.

## Tools

### Context7 - Live Documentation
Fetches current, version-specific docs. Use before implementing unfamiliar libraries or when unsure about API syntax.

### Firecrawl - Web Scraping
Scrapes documentation, Stack Overflow, tutorials, and GitHub repos. Use for deep research and gathering implementation patterns.

### Playwright - Browser Automation
E2E testing, screenshots, form automation. Use for testing UI flows and visual regression.

### Supabase - Backend Management
Direct database queries, auth management, storage, migrations. Use for data inspection and schema changes.

### Sequential Thinking - Problem Solving
Step-by-step reasoning for complex bugs, architecture decisions, and multi-file refactors.

## Workflow

**New Feature:**
1. Context7 → Verify library docs
2. Firecrawl → Research patterns
3. Sequential Thinking → Plan approach
4. Supabase → Prepare schema
5. Playwright → Write tests

**Debugging:**
1. Sequential Thinking → Analyze problem
2. Firecrawl → Search similar issues
3. Supabase → Inspect data state
