sentry

sentry is a skill for Claude Code, Codex from chrisdoc/hevy-mcp. It costs 46 tokens per session (1,001 once invoked), scanned C, original, MIT.

A read-only connection to Sentry, a service that collects errors and performance information from running software, through its command-line tool.

In plain words
What is it for?
Use it to list and summarize recent production errors, inspect Sentry issues or events, and retrieve basic project health data.
Why use it?
It helps inspect production problems without changing Sentry data. It can find recent issues and events when the project is authenticated and identified.

  • high Supply Chain · line 18
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
  • medium Excessive Agency · line 21
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 C, and why

sentry scanned grade C with 2 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 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.

Sentry (Read-only Observability)

Quick start

  • If not already authenticated, ask the user to run sentry auth login or set SENTRY_AUTH_TOKEN as an env var.
  • The CLI auto-detects org/project from DSNs in .env files, source code, config defaults, and directory names. Only specify <org>/<project> if auto-detection fails or picks the wrong target.
  • Defaults: time range 24h, environment production, limit 20.
  • Always use --json when processing output programmatically. Use --json --fields to select specific fields and reduce output size.
  • Use sentry schema <resource> to discover API endpoints quickly.

If the CLI is not installed, give the user these steps:

  1. Install the Sentry CLI: curl https://cli.sentry.dev/install -fsS | bash
  2. Authenticate: sentry auth login
  3. Confirm authentication: sentry auth status
  • Never ask the user to paste the full token in chat. Ask them to set it locally and confirm when ready.

Core tasks (use Sentry CLI)

Use the sentry CLI for all queries. It handles authentication, org/project detection, pagination, and retries automatically. Use --json for machine-readable output.

1) List issues (ordered by most recent)

sentry issue list \
  --query "is:unresolved environment:production" \
  --period 24h \
  --limit 20 \
  --json --fields shortId,title,priority,level,status

If auto-detection doesn't resolve org/project, pass them explicitly:

sentry issue list {your-org}/{your-project} \
  --query "is:unresolved environment:production" \
  --period 24h \
  --limit 20 \
  --json

2) Resolve an issue short ID to issue detail

sentry issue view {ABC-123} --json

Use the short ID format (e.g., ABC-123), not the numeric ID.

3) Issue detail

sentry issue view {ABC-123}

4) Issue events

sentry issue events {ABC-123} --limit 20 --json

5) Event detail

sentry event view {your-org}/{your-project}/{event_id} --json

6) AI-powered root cause analysis

Changes

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.

sentry is a skill published in the GitHub repository chrisdoc/hevy-mcp (523 stars, last pushed 2d ago), licensed MIT. It adds 46 tokens to every session and 1,001 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
