Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00696 |
| Opus 5 | $0.00021 | $0.00348 |
| Sonnet 5 | $0.00008 | $0.00139 |
| Haiku 4.5 | $0.00004 | $0.00070 |
Grade B, and why
exa-web-search-free scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

How it starts
The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Exa Web Search (Free)
Neural search for web, code, and company research. No API key required.
Setup
Verify mcporter is configured:
mcporter list exa
If not listed:
mcporter config add exa https://mcp.exa.ai/mcp
Core Tools
web_search_exa
Search web for current info, news, or facts.
mcporter call 'exa.web_search_exa(query: "latest AI news 2026", numResults: 5)'
Parameters:
query- Search querynumResults(optional, default: 8)type(optional) -"auto","fast", or"deep"
get_code_context_exa
Find code examples and docs from GitHub, Stack Overflow.
mcporter call 'exa.get_code_context_exa(query: "React hooks examples", tokensNum: 3000)'
Parameters:
query- Code/API search querytokensNum(optional, default: 5000) - Range: 1000-50000
company_research_exa
Research companies for business info and news.
mcporter call 'exa.company_research_exa(companyName: "Anthropic", numResults: 3)'
Parameters:
companyName- Company namenumResults(optional, default: 5)
Advanced Tools (Optional)
Six additional tools available by updating config URL:
web_search_advanced_exa- Domain/date filtersdeep_search_exa- Query expansioncrawling_exa- Full page extractionpeople_search_exa- Professional profilesdeep_researcher_start/check- AI research agent
Enable all tools:
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 for more patterns
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
