Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

👌 Use _skills_ in any agent (Codex, Copilot, Cursor, etc...)

[](https://pypi.org/project/skillz/) [](https://pypi.org/project/skillz/)

⚠️ Experimental proof‐of‐concept. Potentially unsafe. Treat skills like untrusted code and run in sandboxes/containers. Use at your own risk.

Skillz is an MCP server that turns Claude-style skills (`SKILL.md` plus optional resources) into callable tools for any MCP client. It discovers each skill, exposes the authored instructions and resources, and can run bundled helper scripts.

💡 You can find skills to install at the [Skills Supermarket](http://skills.intellectronica.net/) directory.

Quick Start

To run the MCP server in your agent, use the following config (or equivalent):

{
"skillz": {
"command": "uvx",
"args": ["skillz@latest"]
}
}

with the skills residing at ~/.skillz

or

{
"skillz": {
"command": "uvx",
"args": ["skillz@latest", "/path/to/skills/direcotry"]
}
}

or Docker

You can run Skillz using Docker for isolation. The image is available on Docker Hub at intellectronica/skillz.

To run the Skillz MCP server with your skills directory mounted using Docker, configure your agent as follows:

Replace /path/to/skills with the path to your actual skills directory. Any arguments after intellectronica/skillz in the array are passed directly to the Skillz CLI.

{
"skillz": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-v",
"/path/to/skills:/skillz",
"intellectronica/skillz",
"/skillz"
]
}
}

Gemini CLI Extension

A Gemini CLI extension is available at intellectronica/gemini-cli-skillz.

Questions

What is the Skillz MCP server?

An MCP server for loading skills (shim for non-claude clients).

What tools does Skillz expose?

1 in total: 1 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Skillz safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Skillz need?

No credential environment variables were found in its source, so it appears to need none.

How current is this page?

The grade is for one exact copy of the source (f6e16c6f32ed), read on 2026-10-01. The repository is watched and re-audited when it changes.
