update

A command that checks whether a newer version of zzop-mcp, a code-analysis tool, is available and explains how to update it.

In plain words
What is it for?
Use it to identify the installed version, compare it with available releases, and receive update instructions.
Why use it?
It lets you decide when to update without changing the installed tool or the analysis results during the check.

Made for: Claude Code.

Per session 21 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 754 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
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

update 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Check for a newer zzop-mcp, and report only

Tell the user which zzop-mcp they have, whether a newer release exists, and — if it does — exactly what to do about it. Do not act on the answer. Not with this command, not as a follow-up, not even if the user seems to want it: taking the update is a decision about when, and the reasons are below.

Why this never installs

A zzop version change is not a patch to a tool that produces the same answer faster. It changes what the analyzer finds, and it invalidates the analysis cache — every cache fingerprint is derived from the source that produced the cached bytes, so a new binary means a full cold run. An update that happened without being asked for would change findings between two sessions with no change in the user's code, which is the exact opposite of the determinism this tool sells. The timing belongs to whoever is going to read the diff in the findings.

The plugin's SessionStart hook follows the same rule: it installs when nothing is installed, and after that it only ever reports. This command is the on-demand half of the same contract.

Steps

  1. Find the installed binary. It lives at $CLAUDE_PLUGIN_DATA/zzop-mcp (zzop-mcp.exe on Windows). That location is decided by .claude-plugin/hooks/bootstrap.sh — read it rather than assuming, if the path does not resolve.
  2. Read the installed version with zzop-mcp version. If the binary is missing or cannot report a version, say so and stop: the fix is a new session (the hook installs on SessionStart), not anything this command should do.
  3. Read the latest published version: curl -fsSL --max-time 10 https://api.github.com/repos/eezz4/zzop/releases/latest and take tag_name. If the request fails, say the check could not run — offline, proxied, or rate-limited — and do not guess from any other source.
  4. Report the comparison. Same version: one line saying it is current. Newer available: name both versions, then give the two ways to take it:
    • delete the binary at $CLAUDE_PLUGIN_DATA/zzop-mcp and start a new session — the hook installs the current release, or
    • download it from https://github.com/eezz4/zzop/releases and put it at that path yourself.

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.

update is a command published in the GitHub repository eezz4/zzop (2 stars, last pushed 16d ago), licensed MIT. It adds 21 tokens to every session and 754 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
