# Web Search (Free)
|
||||
|
||||
Neural search for web, code, company research, people and deep research. No API key required.

```
|
||||
|
||||
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"
|
||||
```
|
||||
|
||||

|
||||
Important: Keep calling with the same research ID until status is 'completed'.
|
||||
|
||||
```bash
|
||||
mcporter call 'exa.deep_researcher_check(researchId: "r_01kj59p3wsm21k8gdrd69nm4sa")'
|
||||
```
|
||||
|
||||
**Parameters:**
|
||||
- `researchId` - The research ID returned from deep_researcher_start tool
|
||||
|
||||
## 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
|
||||
|
||||
## Requirements
