What is beeperbox CLAUDE.md?

A repository instruction file for Beeperbox, a single MCP endpoint that lets an AI agent work with many messaging services through one shared chat and message format. It also documents its one-file Node.js structure, tests, and optional Docker checks.

Use it when developing or testing messaging bridges, attachment handling, the MCP server, or its HTTP safety checks.

It explains how to work with the project without treating each messaging service as a separate integration, and helps avoid using commands or files that do not exist.

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	$0.02307	$0.02307
Opus 5.5	$0.00923	$0.00923
Sonnet 5.5	$0.00461	$0.00461
Haiku 4.5	$0.00231	$0.00231

Security

Grade A, and why

beeperbox CLAUDE.md scanned grade A with 1 finding 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 1mo 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.

What this is

beeperbox exposes every network Beeper bridges (WhatsApp, iMessage, Signal, Telegram, Discord, Slack, Matrix, …) to an AI agent through one MCP endpoint instead of 50 per-platform SDKs. It is not a thin proxy over Beeper's raw API — it is an opinionated verb layer that normalizes everything into one Chat / Message schema.

There is no build step, no framework, no lint/format/TS config, and no root package.json. The entire product is one file: mcp/server.js (CommonJS, Node ≥18, zero runtime deps).

Commands

# Unit tests (node:test — no framework)
node --test mcp/server.test.js
node --test --test-name-pattern 'assertServableSrcUrl' mcp/server.test.js   # single test

# download_asset / attachments E2E against a stub Beeper API (exit 0 = pass)
node scripts/asset-serve-check.js

# MCP tool-contract + HTTP guard matrix (200/403/413/401) — needs docker
bash scripts/mcp-guard-check.sh beeperbox:dev

# First-paint gate (one boot, fresh profile): login window renders + API reachable through the forwarder + HEALTHCHECK healthy — needs docker, curl + python3
bash scripts/first-paint-check.sh beeperbox:dev

# x11vnc auth posture (RFB security types) — needs xvfb + x11vnc
bash scripts/vnc-auth-check.sh

# Container: build from source + wait-for-healthy + probe /v1/info
./scripts/smoke-test.sh
docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d --build

# Lite mode (no Docker) — same file the container runs

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.
