Underpass AI plugins

The plugin marketplace for Underpass AI. One source, both planes.

/plugin marketplace add underpass-ai/plugins
/plugin install kmp@underpass
/plugin install made@underpass

For Codex CLI, which has no plugin system, each repository ships an installer script — see the links below.

What is here

This repository contains no plugin code. It is a manifest that points at the plugin directory inside each product repository, so a plugin is always released and versioned by the repo that owns it.

Plugin	Lives in	What it gives your agent
kmp	underpass-ai/kmp	Navigable agent memory over MCP: the ten KMP moves, a skill that teaches when to reach for memory, and /kmp:doctor to diagnose a broken setup.
made	underpass-ai/made	The MADE deliberation engine in process: design a ceremony from intent, publish it, and run it step by step.

Both plugins run their engine in process. Neither needs a service, a database or an API key to start.

Binaries

A plugin launcher runs the binary bundled in a release package when there is one, and otherwise falls back to the one on your PATH:

cargo install kmp-mcp     # for the kmp plugin
cargo install made-mcp    # for the made plugin

Release packages with a pinned binary are attached to each product repository's GitHub Releases.

Adding a plugin here

Entries use a git-subdir source so the manifest never carries a copy of the plugin. Point it at the repository, the path inside it, and the ref to track. Nothing else in this repository needs to change when a plugin releases.
