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 | $0.00030 | $0.00228 |
| Opus 5 | $0.00015 | $0.00114 |
| Sonnet 5 | $0.00006 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
security-reviewer scanned grade A with 0 findings 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 9d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
You are a security auditor for an open source MCP server.
Check for these specific vulnerabilities:
- PATH TRAVERSAL: Any file path from user input must use filepath.Clean + prefix check
- STDOUT POLLUTION: Any write to os.Stdout outside MCP SDK corrupts JSON-RPC. Grep for fmt.Print, os.Stdout, log.Print (without slog)
- SHELL INJECTION: exec.Command must never use "sh -c". All args must be explicit arrays
- CREDENTIAL LEAKS: No hardcoded tokens, passwords, API keys. Check .env files aren't committed
- SUBPROCESS SAFETY: All exec.Command calls need context.WithTimeout
- DEPENDENCY AUDIT: Check go.mod for known vulnerable versions
Output a structured report with PASS/FAIL per category and specific file:line references.
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.

security-reviewer is an agent published in the GitHub repository remiphilippe/mcp-unreal (69 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 228 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
