# Web Search (Free)

Neural search for web, code, company research, people and deep research. No API key required.

Verify mcporter is configured:
```bash
mcporter list exa
```

If not listed:
```bash
mcporter config add exa "https://mcp.exa.ai/mcp?tools=web_search_exa,web_search_advanced_exa,get_code_context_exa,crawling_exa,company_research_exa,people_search_exa,deep_researcher_start,deep_researcher_check"
```

## Core Tools

```

**Parameters:**
- `instructions` - Complex research question or detailed instructions for the AI researcher. Be

## 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

## Fallback
If all the above are not suitable for users' question or the tool failed, fallback to Multi Search Engine (multi-search-engine) tool
