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 | $0.02107 | $0.02107 |
| Opus 5.5 | $0.00843 | $0.00843 |
| Sonnet 5.5 | $0.00421 | $0.00421 |
| Haiku 4.5 | $0.00211 | $0.00211 |
Grade A, and why
whatsapp-claude-plugin 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 3d 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.

Project Overview
WhatsApp MCP Server plugin for Claude Code — connects WhatsApp as a messaging channel via the linked-device protocol (Baileys). Bidirectional messaging, media, voice transcription, access control, per-group AI personalities, cron tasks. Published on claude.com/plugins.
Tech Stack & Commands
- Runtime: Bun — TypeScript runs directly. No build step.
- Deps (only 4 — no new dependencies without the user's explicit approval):
@modelcontextprotocol/sdk,@whiskeysockets/[email protected],@inquirer/prompts,zod(2 connection payload fields are patched bypatch-baileys.mjsvia postinstall; rc12 brought the upstream message-spoofing and Noise initialization fixes; rc14 is the first release whose spoofing guard still accepts the phone's own sync). - Tests: there IS a test suite — 26
*.test.tsfiles underlib/andscripts/, run withbun test. There is notestscript inpackage.json;bun testfinds them itself. - Linting: Trunk (prettier, markdownlint, shellcheck, shfmt, checkov, trufflehog).
Trunk is not installed on every machine — check before assuming
trunk checkruns.
bun install # install deps (postinstall runs patch-baileys.mjs)
bun server.ts # run the MCP server
bun test # ~130s, spawns real servers — see the warning below
trunk check # lint
trunk fmt # format
Type checking — bun build is NOT a type check. bun build is a bundler: it
resolves and emits, it does not check types, so an out-of-scope or misspelled
identifier bundles happily and tells you nothing. Use tsc directly. This repo
has no tsconfig.json and no local typescript dependency, so pass the options
on the command line (verified 2026-09-08: exit 0, no errors):
bunx --bun typescript@5 --noEmit --skipLibCheck \
--target esnext --module preserve --moduleResolution bundler \
--strict server.ts
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.
