About

Skills is an open registry for reusable AI-agent capabilities: Agent Skills, MCP server listings, agent definitions, prompt packs, workflows, tool connectors, hooks, bundles, evaluation kits and templates.

It is run by Simon-Pierre Boucher, a researcher in Quebec, Canada, who uses Claude Code extensively and wanted two things: a place to publish his own tools properly, and a registry that other researchers and developers could trust enough to build on. It is research infrastructure, not a storefront. Reading and downloading are free and need no account. There is nothing for sale.

Principles

Open by default. Everything public can be read, searched and downloaded by anyone, through the website, a documented REST API and an MCP endpoint. Formats follow open standards: the Agent Skills specification and the Model Context Protocol. The registry adds one small manifest file and leaves the artifact's own files alone.

Inspectable. Every release shows every file, its declared permissions, the findings of the automated checks, and its checksum. You are expected to read what you install, and the site is built to make that easy.

Immutable and attributable. A published version never changes. Each release records who published it. Mistakes are fixed by new versions; dangerous versions are revoked in the open, with a reason.

Honest about trust. The registry checks uploads statically and never executes them. It does not claim that anything is safe. Verification badges say exactly what was verified. There are no stars, no ratings, no seeded content and no invented numbers: counts come from the database, and download figures are labelled as estimates.

Agents as first-class clients, under human control. An agent can publish through a scoped, expiring token that can do that job and nothing else. Exposure, deprecation and revocation need a human's explicit confirmation.

Usable without an account. Nothing a visitor needs is behind a sign-in.

What it is not

• It is not a host for MCP servers. A listing describes a server; the publisher or you run it.
• It is not a security auditor. See Security and trust.
• It is not a marketplace.

State of the project

Skills is new. Accounts and namespaces are created by the operator for now, the command-line client runs from the source repository, and several features are planned rather than built: self-service sign-up, two-factor authentication, organisations, OAuth for the MCP endpoint. The documentation says "planned" wherever that is the case.

Software and licence

The registry software is open source under the MIT licence. Artifacts keep the licences their publishers declare.
