SkillVault · AI Agent Skills

Your AI skills, anywhere, any time, on any device.

SkillVault is cloud storage for AI agent skills. Upload a skill once, reach it through three surfaces: an authenticated vault URL that you can give to ANY AI chatbot on any device, a JSON REST API/MCP for your ChatGPT/Claude/Perplexity connectors, and a CLI wrapper that drops into Claude Code, Cursor, Windsurf, Aider, Codex, or any harness. Your skills, usable by any AI, from anywhere.

DEFINITION

What SkillVault is, in one paragraph

SkillVault is a vault in the cloud, accessible by any AI agent you choose. You register a skill - a name, a description, a Markdown body of instructions, a set of scripts the skill triggers - and SkillVault serves that body to any AI that authenticates with your vault token. The same library shows up on Claude on the web, in Claude Code on your laptop, in ChatGPT via MCP connector, and in Cursor. You write the skill once. Every agent reads the current version.

THREE DIFFERENT WAYS TO ACCESS

Pick the way that fits the AI in front of you.

01

Authenticated Vault URL

One URL, sealed by a token. Paste it into any AI that fetches the web - phone, web chat, screenshot - and it sees the same library.

https://app.skillvault.dev/v/<you>/
02

JSON REST API / MCP

For AI apps with a connector or action config - ChatGPT, Claude.ai, Gemini, Perplexity. Configure once; the AI calls it during conversations. Same URL, same token - REST for automations and scripts, MCP for live connectors.

GET /api/v1/skills
03

CLI Wrapper Skill

For AI harnesses that read skills from a local folder - Claude Code, Cursor, Windsurf, Aider, Codex, and ten more.

HOW IT WORKS

Register. Issue. Use.

  1. REGISTER

    Register a skill

    Add a name, a one-line description, and a body - the instructions an agent should follow. If your skill runs scripts or program files, just ask your agent to install the skill for you.

  2. ISSUE

    Issue the URL

    Your vault is reachable at /v/<you>/. For paid ChatGPT, Claude.ai, Gemini, and Perplexity, register the same URL as an MCP connector; the connector serves the same skills over JSON. The token is bound to your vault; rotate it any time from the dashboard.

  3. USE

    Agents read the vault

    Paste the URL into any AI. The wrapper CLI writes a single-skill fetch into your local skills folder. Either way, the same library shows up.

WHY A VAULT

Why a vault?

AI Agent skills are some of the most popular and helpful files and scripts used today. But, it can be frustrating when you have a skill critical to your process that ONLY EXISTS on your laptop, or at work, or within your browser instance.

We know that pain all too well and that is why we created SkillVault. With SkillVault, your skills are interoperable across platforms and devices.

After all, a Skill isn't just another file. It's a CAPABILITY specific to you. It should be available for use across all instances where you access AI.

FREQUENTLY ASKED

Questions people ask before signing up

What is SkillVault?
SkillVault is a vault in the cloud for your AI skills. You register a skill - a name, a description, a Markdown body of instructions, and any scripts the skill needs - and SkillVault stores it. When any AI you choose asks for it, SkillVault serves the current version. The same skill shows up on Claude on the web, in Claude Code on your laptop, in ChatGPT via MCP, and in Cursor.
Do my skills include scripts?
Yes. A skill can be a Markdown body of instructions, a set of scripts the skill triggers, or both. SkillVault stores the files; when an AI agent reads the skill, it follows the instructions and mimics the scripts inline in its own environment, whatever the device.
How is this different from a prompt library?
A prompt library is a static document you copy and paste. SkillVault is a live endpoint. Every fetch returns your current version of a skill, not a stale copy. The token that protects your vault is separate from your account password, so you can rotate it at any time without touching your sign-in.
Which AI assistants can read from a SkillVault?
Any AI that can fetch a URL or be configured with a custom integration. Claude.ai with web browsing, ChatGPT with Browse, Gemini, Perplexity, and the mobile apps for all of them accept the vault URL directly. Claude Code, Cursor, Windsurf, Aider, Codex, and Cline each get a single-skill fetch written into their local skills folder by the SkillVault CLI. ChatGPT Custom GPTs, Claude.ai custom integrations, and Gemini extensions call the JSON REST API or MCP.
What's the difference between the JSON REST API and MCP?
Same data, different transport. The JSON REST API is a regular HTTP endpoint you hit with a bearer token - useful for automations, scripts, and any tool that speaks HTTP. MCP (Model Context Protocol) is a connector that AI apps register once and then call during a conversation when the AI decides it needs a skill. Both use the same URL and the same vault token, so SkillVault treats them as one surface.
Is my skill content private?
Yes. Vaults are private by default. Each vault is sealed by a unique token; without it, the URL returns 401. We do not index your skill content, we do not share it with other users, and we do not use it to train any model. The full data-handling policy is at /privacy-policy.
How much does SkillVault cost?
Free tier offers 3 skills stored in the vault. Pro is €6.95/month for 50 skills and 1 GB. Power is €18.95/month for unlimited skills, 10 GB, and priority routing. All live tiers include all surfaces — Vault URL, JSON API, MCP Server, and CLI.
What happens to my data if I cancel?
You keep your paid tier until the end of the period you've already paid for. When that period ends, your subscription moves to the free tier — your vault stays live with the free-tier caps (3 skills, 100 MB). You can re-subscribe at any time to restore your paid tier. We never delete your data on cancellation; the 30-day hard-delete only runs if you explicitly click "Delete Account" in the dashboard.
