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 | $0.00132 | $0.00132 |
| Opus 5.5 | $0.00053 | $0.00053 |
| Sonnet 5.5 | $0.00026 | $0.00026 |
| Haiku 4.5 | $0.00013 | $0.00013 |
Grade A, and why
meta-business-mcp AGENTS.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 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
Meta Business MCP Instructions
- Keep this repository open-source-safe.
- Do not add Clara-specific prompts, account IDs, client names, workflows, CRM mappings, budgets, thresholds, or private playbooks.
- Do not add live Meta credentials, tokens, app secrets, user data, lead data, or production payloads.
- Do not add generic Graph API proxy tools. Every Meta API operation must be allowlisted by name.
- Default to read-only behavior. Write, messaging, publishing, delete, budget-change, and campaign-activation behavior must remain absent unless explicitly requested in a later security-reviewed milestone.
- Tests must not require live Meta credentials.
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.
