hopper-debugger from steipete/agent-scripts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Hopper debugging: macOS/iOS binaries, ObjC/Swift symbols, dyld, LLDB.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hopper Debugger
Use Hopper through `mcporter` as a queryable disassembler, then combine the result with local source, LLDB, logs, and focused repros.
## Setup (one time)
Hopper 6.0+ **ships its own MCP server**. Do not install a third-party one.
```bash
mcporter config add hopper --scope home \
--command "/Applications/Hopper Disassembler.app/Contents/MacOS/HopperMCPServer" \
--description "Hopper Disassembler built-in MCP server (stdio)"
```
`--scope home` is required. The default scope is **project**, which writes `config/mcporter.json` into whatever repo you are standing in (untracked repo dirt, lost with the worktree).
Verify:
```bash
MCPORTER_LIST_TIMEOUT=25000 timeout 40 mcporter list hopper --brief
```
## Call convention — the one that bites
**Always pass arguments with `--args`. Never `--params`.** `mcporter` accepts an unknown `--params` flag *silently*, drops the payload, and the call arrives with no arguments. Hopper then answers `Document not found.`, which reads like a licensing or state problem and is not.
```bash
# WRONG — arguments silently dropped, fails with "Document not found."
mcporter call hopper.list_segments --params '{"document":"AppKit"}'

How to install
mdr add steipete/agent-scripts/hopper-debugger@sha256:026e54b87ef708b3The line at the top of this page pins the label git:20260809.41009b1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
