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 | $0.02315 | $0.02315 |
| Opus 5 | $0.01157 | $0.01157 |
| Sonnet 5 | $0.00463 | $0.00463 |
| Haiku 4.5 | $0.00231 | $0.00231 |
Grade A, and why
whatsapp-mcp-extended 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 12d 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.

whatsapp-bridge/ (Go): WhatsApp API connection via whatsmeow, message handling, webhook delivery, REST API whatsapp-mcp-server/ (Python): MCP protocol implementation, message search, media handling, contact management whatsapp-webhook-ui/: Web interface for webhook configuration
Commands
Docker (recommended)
docker network create n8n_n8n_traefik_network # first time only
docker-compose up -d # start all services
docker-compose logs -f whatsapp-bridge # watch for QR code
docker-compose build # rebuild all
docker-compose build whatsapp-bridge # rebuild specific
IMPORTANT: No hot-reload - code is COPY'd into containers at build time. After any code changes:
docker-compose build <service> # rebuild changed service
docker-compose up -d <service> # restart with new image
Development
# Bridge (Go 1.24+)
cd whatsapp-bridge && go run main.go
cd whatsapp-bridge && go test ./...
# MCP Server (Python 3.11+, requires uv)
cd whatsapp-mcp-server && uv sync
cd whatsapp-mcp-server && uv run python whatsapp.py
# Webhook UI
cd whatsapp-webhook-ui && python3 -m http.server 8089
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.
