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 | $0.03028 | $0.03028 |
| Opus 5 | $0.01514 | $0.01514 |
| Sonnet 5 | $0.00606 | $0.00606 |
| Haiku 4.5 | $0.00303 | $0.00303 |
Grade A, and why
vibo-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 7d 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 — 211 lines — stays where its author put it; the contents beside it link to each section on GitHub.
vibo-mcp
MCP server for Vibo. Wraps the Vibo consumer GraphQL API
(https://api.vibodj.com/v2/graphql) and exposes 39 host/couple tools to Claude
over stdio (15 reads + 24 writes/actions, confirm-gated where they mutate). Built on @chrischall/mcp-utils
(runMcp, textResult, toolAnnotations, schemaConfirm, error classes).
Commands
npm run build # tsc + esbuild bundle → dist/index.js + dist/bundle.js
npm test # vitest run
npm run test:watch # vitest watch
npm run test:coverage # vitest run --coverage (v8 reporter, no thresholds)
Run locally (requires built dist/ + credentials):
[email protected] VIBO_PASSWORD=… node dist/index.js
Tool naming
All tools are prefixed vibo_ (e.g. vibo_list_sections, vibo_add_song_to_section).

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.
