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 | $0.00885 | $0.00885 |
| Opus 5.5 | $0.00354 | $0.00354 |
| Sonnet 5.5 | $0.00177 | $0.00177 |
| Haiku 4.5 | $0.00089 | $0.00089 |
Grade A, and why
agentvault 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentVault
AI-native credential management SaaS for autonomous AI agents.
What It Does
- Stores API keys/secrets with Fernet column-level encryption
- Issues unique API keys to registered "agent identities"
- Proxy endpoint: agents call
/api/v1/vault/get/{credential_name}with their API key - Per-agent daily/monthly spending budgets
- Full audit logs of every vault access
- MCP server interface (stdio + SSE on
/mcp) - Stripe billing (Free / Pro $49 / Business $149 / Enterprise $499)
Stack
- Backend: FastAPI (Python 3.12) on Railway
- Database: Postgres (asyncpg + SQLAlchemy async)
- Encryption: Fernet (cryptography lib) — column-level, not just at-rest
- Auth: Clerk (user) + custom API keys (agents)
- Payments: Stripe Checkout + webhooks
- Alerts: SendGrid
- MCP: FastMCP library

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.

agentvault CLAUDE.md is an instructions file published in the GitHub repository bch1212/agentvault (0 stars, last pushed 4mo ago), licensed MIT. It adds 885 tokens to every session, about $0.0035 per session on Opus 5.5. A static security scan graded it A with 0 findings.
