claude-mpm: Hook for Claude Code

.claude/settings.json

PostToolUse is a hook for Claude Code from bobmatnyc/claude-mpm. Its token cost is not measured, scanned A, original, no licence file.

An after-tool hook that runs commands when the agent finishes certain file-editing tools, including Write, MultiEdit, Edit, and NotebookEdit.

In plain words
What is it for?
It helps trigger the two configured claude-hook commands after supported file changes.
Why use it?
It lets a project run follow-up checks or actions automatically after those edits, instead of relying on the agent to remember them.

Hook for Claude Code

Written for Claude Code: installed under .claude/.

This is bobmatnyc/claude-mpm's own configuration. It tells Claude Code how to work on claude-mpm 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 claude-mpm configures →

One of 9 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 8 are separate, each on its own page.

Security

Grade A, and why

PostToolUse 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 commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What else settings.json configures

This page is one entry in a file that holds 9. Installing the file brings all of them; each is measured and scanned on its own page.

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.
