Agent Skills (Claude Skills)
Ready-to-use skills for Claude Code. Each skill teaches Claude how to use Exa search for a specific task. Copy the content inside a dropdown and paste it into Claude Code — it handles the rest.
Company Research
Copy the content below and paste it into Claude Code. It will set up the MCP connection and skill for you.
Step 1: Install or update Exa MCP
If Exa MCP already exists in your MCP configuration, either uninstall it first and install the new one, or update your existing MCP config with this endpoint. Run this command in your terminal:
claude mcp add --transport http exa "https://mcp.exa.ai/mcp?tools=web_search_advanced_exa"

# Company Research
## Tool Restriction (Critical)
ONLY use `web_search_advanced_exa`. Do NOT use `web_search_exa` or any other Exa tools.
## Token Isolation (Critical)
Never run Exa searches in main context. Always spawn Task agents:
- Agent runs Exa search internally
- Agent processes results using LLM intelligence
- Agent returns only distilled output (compact JSON or brief markdown)
- Main context stays clean regardless of search volume
## Dynamic Tuning
No hardcoded numResults. Tune to user intent:
- User says "a few" → 10-20
- User says "comprehensive" → 50-100
- User specifies number → match it
- Ambiguous? Ask: "How many companies would you like?"
## Query Variation
Exa returns different results for different phrasings. For coverage:
- Generate 2-3 query variations
- Run in parallel
- Merge and deduplicate
## Categories
Use appropriate Exa `category` depending on what you need:
- `company` → homepages, rich metadata (headcount, location, funding, revenue)
- `news` → press coverage, announcements
- `tweet` → social presence, public commentary
- `people` → LinkedIn profiles (public data)
- No category (`type: "auto"`) → general web results, deep dives, broader context
Start with `category: "company"` for discovery, then use other categories or no category with `livecrawl: "fallback"` for deeper research.
### Category-Specific Filter Restrictions
When using `category: "company"`, these parameters cause 400 errors:
- `includeDomains` / `excludeDomains`
- `startPublishedDate` / `endPublishedDate`
- `startCrawlDate` / `endCrawlDate`
When searching without a category (or with `news`), domain and date filters work fine.
**Universal restriction:** `includeText` and `excludeText` only support **single-item arrays**. Multi-item arrays cause 400 errors across all categories.
## LinkedIn
Public LinkedIn via Exa: `category: "people"`, no other filters.
Auth-required LinkedIn → use Claude in Chrome browser fallback.
## Browser Fallback
Auto-fallback to Claude in Chrome when:
- Exa returns insufficient results
- Content is auth-gated
- Dynamic pages need JavaScript
## Examples
### Discovery: find companies in a space
```
web_search_advanced_exa {
"query": "AI infrastructure startups San Francisco",
"category": "company",
"numResults": 20,
"type": "auto"
}
```
### Deep dive: research a specific company
```
web_search_advanced_exa {
"query": "Anthropic funding rounds valuation 2024",
"type": "deep",
"livecrawl": "fallback",
"numResults": 10,
"includeDomains": ["techcrunch.com", "crunchbase.com", "bloomberg.com"]
}
```
### News coverage
```
web_search_advanced_exa {
"query": "Anthropic AI safety",
"category": "news",
"numResults": 15,
"startPublishedDate": "2024-01-01"
}
```
### LinkedIn profiles
```
web_search_advanced_exa {
"query": "VP Engineering AI infrastructure",
"category": "people",
"numResults": 20
}
```
