## Advanced Tools (Optional)

Six additional tools available by updating config URL:

- `people_search_exa` - Professional profiles
- `deep_researcher_start/check` - AI research agent

**Enable all tools:**
```bash
mcporter config add exa-full "https://mcp.exa.ai/mcp?tools=web_search_exa,web_search_advanced_exa,get_code_context_exa,deep_search_exa,crawling_exa,company_research_exa,people_search_exa,deep_researcher_start,deep_researcher_check"

# Then use:
mcporter call 'exa-full.deep_search_exa(query: "AI safety research")'
```

## Tips

- Web: Use `type: "fast"` for quick lookup, `"deep"` for thorough research
- Code: Lower `tokensNum` (1000-2000) for focused, higher (5000+) for comprehensive
- See [examples.md](references/examples.md) for more patterns
