Pynchy

🦞 Pynchy (pronounced "Pinchy") — A personal AI assistant like OpenClaw done right. Security first, modular, written in Python.

Why Pynchy?

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.

  • ZeroClaw looks great actually, but I don't know how to write in Rust.
  • Happy looks great, but ultimately is a remote terminal to Claude Code. I want to add my own security features. Also, I am not fluent in TypeScript.
  • NanoClaw is too minimalist.
  • OpenClaw is a massive pile of overcooked spaghetti code. Ain't no way I'm running that security nightmare on my machine.
  • pi mono is a less crazy project, which OpenClaw built on top of. It doesn't have the security features I want.

Features

  • Agents run in containers, with process, filesystem, and network isolation.
  • Built-in plugins ship with the monorepo; third-party plugins are discoverable via Python entry points.
  • Uses LiteLLM as the LLM gateway, which gives you a bunch of features out of the box:
  • Automatic load balancing across APIs, to soak up your various allowances from different providers.
  • Access to 100+ LLM providers
  • Cost tracking and budget management.
  • Rate limiting
  • MCP gateway — manages external MCP tool servers with per-workspace access control and on-demand Docker lifecycle.
  • (see the LiteLLM docs for more details)
  • Eight types of plugins — agent cores, skills, channels, service handlers, container runtimes, workspaces, observers, and tunnels.
  • Persistent memory with BM25-ranked full-text search — agents save and recall facts across sessions.
  • Recurring tasks scheduled at specific times or intervals.
  • Policy groups to prevent lethal trifecta prompt injection attacks.

Integrations

Built-in plugins provide integrations with external services, and they're all pluggable — see plugin authoring to add your own.

Integration What it does
WhatsApp 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

FAQ

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.
