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 | $0.00067 | $0.00189 |
| Opus 5.5 | $0.00027 | $0.00076 |
| Sonnet 5.5 | $0.00013 | $0.00038 |
| Haiku 4.5 | $0.00007 | $0.00019 |
Grade A, and why
setup-brain 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 2mo 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
setup-brain
Read SETUP.md in the repo root and execute every step in order, exactly as
written. It is idempotent and cross-platform.
- Run all commands from the repo root using the
.venvPython. - Ask the user only where SETUP.md explicitly says to ask (confirming or choosing the vault, or when Ollama needs installing).
- Do not skip the verification step.
- When done, tell the user to restart their MCP client and list the available
braintools.
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.

setup-brain is a skill published in the GitHub repository irahulstomar/brain-mcp (6 stars, last pushed 5mo ago), licensed MIT. It adds 67 tokens to every session and 189 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
