+
+# Exa Web Search (Free)
+
+Neural search for web, code, and company research. No API key required.
+
+## Setup
+
+Verify mcporter is configured:
+```bash
+mcporter list exa
+```
+
+If not listed:
+```bash
+mcporter config add exa https://mcp.exa.ai/mcp
+```
+
+## Core Tools
+
+### web_search_exa
+Search web for current info, news, or facts.
+
+```bash
+mcporter call 'exa.web_search_exa(query: "latest AI news 2026", numResults: 5)'
+```
+
+**Parameters:**
+- `query` - Search query
+- `numResults` (optional, default: 8)
+- `type` (optional) - `"auto"`, `"fast"`, or `"deep"`
+
+### get_code_context_exa
+Find code examples and docs from GitHub, Stack Overflow.
+
+```bash
+mcporter call 'exa.get_code_context_exa(query: "React hooks examples", tokensNum: 3000)'
+```
+
+**Parameters:**
+- `query` - Code/API search query
+- `tokensNum` (optional, default: 5000) - Range: 1000-50000
+
+### company_research_exa
+Research companies for business info and news.
+
+```bash
+mcporter call 'exa.company_research_exa(companyName: "Anthropic", numResults: 3)'
+```
+
+**Parameters:**
+- `companyName` - Company name
+- `numResults` (optional, default: 5)
+
+## Advanced Tools (Optional)
+
+Six additional tools available by updating config URL:
+- `web_search_advanced_exa` - Domain/date filters
+- `deep_search_exa` - Query expansion
+- `crawling_exa` - Full page extraction
+- `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

+## Parameter Guidance
+
+### `type` parameter (web_search_exa)
+- `"auto"` - Balanced search (default)
+- `"fast"` - Quick results, less comprehensive
+- `"deep"` - Thorough research, slower but more complete
+
+### `tokensNum` parameter (get_code_context_exa)
+- `1000-2000` - Focused queries, specific examples
+- `3000-5000` - Standard documentation lookup (default: 5000)
+- `5000-10000` - Comprehensive guides and tutorials
+- `10000-50000` - Deep dives, full API documentation
+
+### `numResults` parameter
+- `3-5` - Quick lookup, specific answer
+- `5-8` - Standard research (default for web: 8, company: 5)
+- `10+` - Comprehensive research, multiple perspectives
+
