A home for
your agent skills.
Serve Markdown instructions to your agents through the Model Context Protocol (MCP). Run locally, self-host, or author and version private skills at skillar.sh/skills.
Hosted MCP is live at https://skillar.sh/mcp. Connect Codex or Claude Code with OAuth.
Choose how
you run skillar.
Use the open-source tools on your own infrastructure, or publish private skills to your hosted account. The choice is who runs the server, not whether your skills stay in Markdown.
| Setup | Local / self-hosted | Hosted account |
|---|---|---|
| Availability | Available in the repository | Hosted MCP with OAuth; private skill authoring and versions |
| Endpoint | Your local or self-hosted URL | https://skillar.sh/mcp |
| Operations | Your config, deployment and credentials | Private skills at skillar.sh/skills; managed OAuth connections |
| Pricing | Open-source software; your infrastructure costs | Not announced |
Local CLI and client integrations: MIT. Registry server and Cloudflare Worker: AGPL-3.0-only.
Remote self-hosting requires your own configuration and release validation. A skill read is not permission to execute its instructions.
Your account.
Your activity.
Sign in with Google, connect a device, and choose what it may upload. Review its uploaded snapshots in the remote dashboard. Every device starts local only.
Author and version private skills at skillar.sh/skills, then approve Codex or Claude Code over MCP with OAuth. Signing in stores your Google ID, email, name, picture and sign-in times. Hosted pricing is not announced.
Sign in with Google
Google handles authentication. skillar stores your Google ID, email, name, picture and first and latest sign-in times, keeps your session in a signed, secure cookie, and retains no Google tokens.
Connect a device
Download a one-time grant from the dashboard and connect the local CLI. Then save separate upload consent for that device. Connecting alone uploads nothing.
Review activity
Inspect Sessions, Workspaces, Flow and Heatmap from uploaded snapshots. Views refresh when consented uploads change; capture times and report status show data freshness.

Local setup detects supported runtimes. Capture coverage and remote integration vary by client.
Write. Serve.
Put it to work.
Instructions stay in files you own. Agents find the right skill and read it when the task calls for it.
Start with a skill
A skill is a folder with a
SKILL.mdfile: a name, a description and the instructions your agent reads when a task calls for them.Give it a home
Index existing folders locally, configure your own remote registry, or author and version private skills at skillar.sh/skills.
Connect your agents
Search through
search_skills. Read the selected skill through MCP resources. Load the details on demand, not the whole library.
Just Markdown.
Actual know-how.
No new authoring language. A skill bundles instructions with the files that support them.
The local catalog indexes your folders in place. The registry exposes skills through MCP discovery and resource reads.

The local CLI can detect your runtimes, configure MCP, and install a background service. Preview its changes before you apply them.

Upgrading from gisool? Migrate firstnpm install -g skillarThen run skillar init. Installing over gisool collides on the gisool command, so migrate first.

Good questions.
What is an agent skill?
A folder containing a SKILL.md instruction file and optional supporting files. The name and description help an agent discover it; the body carries the actual instructions.
Can I use skillar today?
Yes. Install the local CLI with npm install -g skillar. Run skillar init --dry-run to preview setup changes. macOS or Linux and Node.js 24.15+ are required. If you are upgrading from gisool, read the migration guide first.
Is the hosted service live?
Yes. Author and version private skills at skillar.sh/skills. Connect Codex or Claude Code to https://skillar.sh/mcp with OAuth to read the skills you publish. Activity uploads require a connected device and separate explicit consent. Hosted pricing is not announced. The hosted accounts section describes the journey.
Does every MCP client work?
Skills require a host that can discover and read MCP resources. The repository includes runtime-specific integrations; compatibility and capture coverage vary. Check the protocol and compatibility guide for your client.
Where does my local data go?
The local daemon listens on loopback, uses a local bearer token, and stores indexed skills and captured session activity in local SQLite. Cloud uploads are off by default. Connect a device and save explicit upload consent in the dashboard to enable them. Your connected agent and model provider handle data separately.
Can I host a registry for my team?
Yes. The repository includes a Node.js registry and a Cloudflare Worker for authenticated distribution from private R2 releases. You provide infrastructure and credentials. See the deployment guide.
