What is install-realtycalendar-mcp?

An installation guide for connecting RealtyCalendar webhooks and its MCP server to an AI client. A webhook is a URL that receives automatic event notifications from another service.

Use it to start the local RealtyCalendar webhook receiver, connect its printed URL to RealtyCalendar, check the booking mirror, and install the MCP server in an AI client.

It explains which installation steps can be done automatically and which require commands on the user’s computer. It also warns about changing temporary public URLs and avoids promising access the installer cannot have.

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	$0.00043	$0.00634
Opus 5	$0.00022	$0.00317
Sonnet 5	$0.00009	$0.00127
Haiku 4.5	$0.00004	$0.00063

Security

Grade A, and why

install-realtycalendar-mcp 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 9d 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.

What it actually says

Установка realtycalendar-mcp

Помоги пользователю подключить его аккаунт RealtyCalendar к AI-агенту. Два независимых куска — ставь тот, что нужен, можно оба.

Честная граница (бутстрап-парадокс)

Если ты агент в песочнице (Cowork), ты не можешь прописать хостовый MCP-сервер в конфиг машины пользователя — нет доступа в его терминал/ФС. Тогда:

дай пользователю команды для копипаста, или
пусть ставит Claude Code локально (install.py отработает на его машине), или
дабл-клик по установщику. Не обещай то, что не можешь сделать из песочницы.

Кусок 1 — приём вебхуков (работает без токена, ставь первым)

pip install realtycalendar-mcp (или pipx).
rc-webhook start — поднимет локальный приёмник и публичный URL через cloudflared.
- Если cloudflared не установлен — подскажи brew install cloudflared (macOS) или релиз с GitHub.
Пользователь вставляет напечатанный URL в RealtyCalendar: Настройки → CRM-интеграции → «Введите URL нового Webhook» → Запустить.
Готово: брони пишутся в локальное зеркало. Проверка — тул rc_mirror_status.

Предупреди: URL trycloudflare меняется при рестарте — тогда вставить новый.

Кусок 2 — MCP-сервер в AI-клиент

Claude Desktop: python3 install.py --client claude-desktop, затем перезапуск Claude Desktop.
Claude Code: python3 install.py --client claude-code → выполнить напечатанный claude mcp add ….
Codex: --client codex.

Кусок 3 — токен для read-API (опционально)

Read-тулы (объекты, календарь, загрузка) требуют партнёрский токен. Его нет в самообслуживании: пользователь пишет на [email protected], получает токен, затем в чате — «добавь кабинет RealtyCalendar, токен …» (rc_add_cabinet). Проверка: rc_check_auth.

Проверка

rc_mirror_status — сколько броней/событий в зеркале.
rc_check_auth — виден ли токен (маскированный).
«кто заезжает сегодня» → rc_todays_checkins.

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.

Your next session starts cold. No memory of what you built, what broke, what you decided. Every memory you write is a gift to that future session. The richer the memory, the less time re-learning.
