mailganer-api-mcp: Skill for Cursor

.cursor/skills/manage-api-docs/SKILL.md

manage-api-docs is a skill for Cursor from dkanster/mailganer-api-mcp. It costs 61 tokens per session (932 once invoked), scanned A, original, MIT.

A skill for managing a local cache of Mailganer REST API documentation and making live API calls. REST APIs are web endpoints that programs use to exchange data through requests.

In plain words
What is it for?
Use it to sync Mailganer API and Postman documentation, search the cached pages, check documentation status, and call Mailganer endpoints when an API key is configured.
Why use it?
It keeps API reference pages available locally and provides a documented process for preparing, checking, and sending requests.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is dkanster/mailganer-api-mcp's own configuration. It tells Cursor how to work on mailganer-api-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mailganer-api-mcp configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 scripts/sync-api-docs.py.

Reuse

Borrowing it

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.

Security

Grade A, and why

manage-api-docs 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 5d 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.

Управление документацией Mailganer API

MCP-сервер mailganer-api — локальный кэш документации и live-вызовы REST API (с MAILGANER_API_KEY).

Установка

git clone https://github.com/dkanster/mailganer-api-mcp.git
cd mailganer-api-mcp
./setup.sh .

Reload MCP в Cursor: Settings → MCP → Reload.

MAILGANER_API_KEY нужен для live-вызовов API (call_mailganer_api, prepare_api_call). Для управления документацией ключ не обязателен.

POSTMAN_API_KEY нужен для MCP-сервера postman (коллекции и workspace в вашем аккаунте) и для записи в коллекцию через scripts/add-missing-postman-requests.py. Локальный кэш Postman (docs/postman/) синхронизируется из публичной коллекции и работает без ключа.

Типовые сценарии

Вызвать API

  1. get_api_credentials_status — проверить ключ
  2. prepare_api_call с slug — method, path, example body
  3. call_mailganer_api — выполнить запрос

Prompt call-endpoint объединяет эти шаги.

Обновить весь кэш

Инструмент sync_documentation с target: "all".

Или в терминале:

python3 scripts/sync-api-docs.py
python3 scripts/sync-postman.py

Статус кэша

get_doc_status — когда последний sync, сколько страниц, ошибки, Postman.

get_cache_health — быстрая проверка, достаточно ли docs/ для работы (после pip install без clone часто ready: false).

Найти метод

  1. search_api_docs — по тексту страниц (параметры, примеры, заголовки)
  2. search_postman — по Postman-коллекции
  3. get_api_endpoint_doc — страница docs вместе с Postman-запросами
  4. get_linked_postman_request — Postman-запрос вместе со страницами docs

Проверить, изменилась ли страница на сайте

check_doc_page с slug — сравнивает кэш с live-версией и показывает diff.

«Дыры» в связях docs ↔ Postman

list_crosslink_gaps — что не связано и почему (doc_notes в docs/manual-crosslinks.json).

Ручные связи правятся в docs/manual-crosslinks.json, затем rebuild_doc_crosslinks.

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.
