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 | $0.00543 | $0.00543 |
| Opus 5 | $0.00271 | $0.00271 |
| Sonnet 5 | $0.00109 | $0.00109 |
| Haiku 4.5 | $0.00054 | $0.00054 |
Grade A, and why
gainium-mcp CLAUDE.md 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.

📚 Platform knowledge base
A curated, auto-updated AI-agent knowledge base for the whole Gainium platform lives in the
private repo gainium-0-knowledge (github.com/aressanch/gainium-0-knowledge).
Local checkouts — Mac: ~/Git/Gainium Local/0-knowledge · VPS: /root/git/0-knowledge.
Consult it before non-trivial work: ARCHITECTURE.md (service graph + danger boundaries),
subsystems/<area>.md (how each area works & breaks), bug-patterns/, runbooks/,
domain/glossary.md. Query 3.7k historical bugs by symptom:
python3 <kb>/_raw/scripts/bugs.py find "<terms>". It is auto-enriched daily from agent session digests.
MCP server exposing Gainium bots/deals/balances to AI assistants. Transports: stdio (default) or HTTP
(:3000). Map: ../0-knowledge/ARCHITECTURE.md.

Coupling — depends on the PUBLIC api.gainium.io contract
- Calls main-app public REST via
GAINIUM_API_BASE_URL(prodhttps://api.gainium.io, dev:7503), HMAC-SHA256 signed (src/gainium-client.ts):/api/v2/bots/*,/api/v2/deals/*,/api/v2/user/*,/api/v2/screener,/api/curated-presets, … - OAuth: validates bearer tokens via main-app
/oauth/introspect(GAINIUM_INTROSPECTION_URL,src/server.ts) expecting{active,apiKey,apiSecret,scope,aud,restrictions}. - These contracts are owned by main-app (root Danger List §2). If a tool breaks, the fix usually belongs
on main-app's
/api/v2or/oauth/introspect— don't paper over it here.
Rules
- Tools carry MCP safety annotations (
readOnlyHintfor GET,destructiveHintfor writes) — keep them accurate; they gate what an assistant may auto-run.
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.
- 9d ago First seen · 32 lines · 543 tokens per session scan A e60c344d81d1
gainium-mcp CLAUDE.md is an instructions file published in the GitHub repository Gainium/gainium-mcp (2 stars, last pushed 4d ago), licensed MIT. It adds 543 tokens to every session, about $0.0027 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 2026-08-31.
