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 | $0.01081 | $0.01081 |
| Opus 5.5 | $0.00432 | $0.00432 |
| Sonnet 5.5 | $0.00216 | $0.00216 |
| Haiku 4.5 | $0.00108 | $0.00108 |
Grade A, and why
mcp-sentry AGENTS.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.
How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mcp-sentry — инструкции для агента
MCP-сервер для Sentry API. Точка входа — src/index.ts. Node.js ≥ 22 (engines, CI, .nvmrc). После правок: npm run compile, поднять version в package.json, push в master (CI → dist + git-тег v{version}) и reload MCP в Cursor.
Подробности для людей — README.md. История версий — CHANGELOG.md. План апгрейда на @sentry/api — sentry-api-upgrade.md.
Конфигурация
npx (без клона)
{
"command": "npx",
"args": ["-y", "github:CynepHy6/mcp-sentry#semver:^1"],
"env": {
"SENTRY_AUTH": "token",
"SENTRY_HOST": "https://sentry.example.com"
}
}
Креды только в env MCP-конфига. dotenv из .env пакета не рассчитан на этот режим.
Релиз: bump version в package.json → push master → CI → dist + git-тег v{version}.
Скрипт сборки — compile, не build: см. .cursor/rules/mcp-server-development.mdc (npm/cli#4003). На dist уходит runtime-only package.json без devDependencies и compile-скриптов.
Ref в args:
"github:CynepHy6/mcp-sentry#semver:^1"
"github:CynepHy6/mcp-sentry#v1.2.0"
"github:CynepHy6/mcp-sentry#semver:1.2.0"
Node.js (nvm)
В корне репозитория — .nvmrc с версией 22. Перед npm install / compile / test:
nvm use # читает .nvmrc
node --version # ожидается v22.x
Если Node 22 ещё не установлен: nvm install 22. Чтобы не переключать вручную в каждой сессии: nvm alias default 22.
Важно: /usr/bin/node может оставаться на 20 — для разработки опираться на nvm use, не на системный node.
Локальный клон
git clone https://github.com/CynepHy6/mcp-sentry.gitnvm use(см. выше).envв корне репозитория (см..env.example).index.tsподхватывает его черезdotenvизbuild/→../.env.- Cursor MCP:
node+build/index.js; переменные можно задать вenvблока MCP или только в.env. Для локального клона вcommandлучше абсолютный путь к node из nvm, например~/.nvm/versions/node/v22.22.3/bin/node, иначе Cursor может подхватить системный Node 20.
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.
