What is whatsapp-mcp-extended CLAUDE.md?

A project guide for a WhatsApp MCP server that connects AI tools to personal WhatsApp accounts through a Go bridge, a Python server, a web interface, and SQLite databases.

Use it to develop or operate WhatsApp message handling, search, webhooks, the bridge, the Python MCP server, the web UI, and the containerized services.

It explains how the messaging bridge, search server, webhook interface, storage, ports, and Docker setup fit together.

Token cost

What it costs to keep this loaded

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 5.5	$0.00926	$0.00926
Sonnet 5.5	$0.00463	$0.00463
Haiku 4.5	$0.00231	$0.00231

Security

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 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.

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.
