Pynchy — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Pynchy (MCP Server) and scored it 65/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 6 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

```See INSTALL.md — review scripts/bootstrap.sh (sha-pinned) before running it yourself.The text {match} is the classic direct prompt-injection phrasing. Placed in a skill body that the agent reads as trusted instructions, it tries to make the agent abandon its prior rules and follow whatever comes next — a full system-prompt override.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.

<p align="center"> <em>🦞 Pynchy</em> (pronounced "Pinchy") — A personal AI assistant like <a href="https://github.com/openclaw/openclaw">OpenClaw</a> done right. Security first, modular, written in Python. </p>
Everyone is writing their own AI assistant. Why write another one? Mainly because I wanted something written in Python — that's what I'm most comfortable with.
Built-in plugins provide integrations with external services, and they're all pluggable — see plugin authoring to add your own.
| Integration | What it does |
|---|---|
| Messaging channel via linked device | |
| Slack | Messaging channel with browser-based token extraction |
| X (Twitter) | Post, like, reply, retweet, and quote via browser automation |
| CalDAV | Calendar access (Nextcloud, etc.) — list, create, delete events |
| Jupyter Notebooks | Per-workspace notebook server with MCP tools |
| Google Drive | File access via OAuth2 MCP server |
See the [installation guide](https://pynchy.ricardodecal.com/install/).

| Section | What it covers |
|---|---|
| Usage | Day-to-day operation, groups, scheduled tasks |
| Plugin authoring | Writing plugins: channels, skills, MCP servers |
| Architecture & Design | Container isolation, message routing, IPC, security |
| Contributing | How to contribute — plugins, fixes, docs, and more |
What messaging channels are supported? WhatsApp and Slack have first-party plugins. Channels are pluggable — write a plugin to add new ones.
Why Apple Container instead of Docker? On macOS, Apple Container is lightweight and optimized for Apple silicon. Docker works too and is used as a fallback. On Linux, Docker is the only option.
Is this secure? Agents run in containers, not behind application-level permission checks. They can only access explicitly mounted directories. See the security model for details.
How do I debug issues? Ask Pynchy. "Why isn't the scheduler running?" "What's in the recent logs?"
Huge thanks to NanoClaw. Pynchy started as a Python port of NanoClaw.
