AI AGENT LIBRARY
Package and share agents. Skills, MCPs and prompts in one place.
Teams rebuild the same agent setup again and again: skills in one place, an MCP server in another, prompts in a document and keys in a chat. Joyst is a private AI agent library where you catalogue reusable agent packages, so each setup stays consistent and has a clear owner. Joyst packages and shares the setup. It does not orchestrate your agents, and it is not a public agent marketplace.
PRIVATE TO YOU
AI agent library for your organisation
- Catalogue reusable setups
Know exactly what the support agent or the research agent includes, and who may publish a new version. Packages stay inside your organisation.
- Packaging only
Bundle skills, MCP servers and prompts, and refer to secrets in the vault. Joyst packages the setup. It does not orchestrate multi-agent workflows.
- Private library
The library is private to your organisation. There is no public storefront for downloading agents.
WHAT’S IN A PACKAGE
What’s in an agent package
- Skills from the registry
Pull published skills from the skills registry, so agent guidance stays versioned.
- MCPs from the catalogue
Use approved servers from the private MCP catalogue instead of one-off connections.
- Prompts from prompt management
Reuse approved prompts, so the package holds the wording your team has agreed.
- Secrets by reference
Point to entries in the vault. No keys are pasted into the package.
ACROSS TOOLS
The same setup across harnesses and AI tools.
- Build once
Package a setup once and use it across the tools your team works in. Nobody has to rediscover the same MCP servers and prompts each time they open a new tool.
- One package, many tools
The catalogue holds one version of each setup, which you use across harnesses and tools instead of rebuilding it for each one.
- Clear ownership
Every package has an owner. The team uses the approved version wherever they work.
TEAM CATALOGUE
Share agents with the team
- Assemble once
Combine skills, MCP servers and prompts into one package, then share it.
- Version and approve
Publish for team use with a clear owner, so people run the approved setup rather than a private copy.
- Easy to find
The private library shows the team what the support agent includes, without searching Slack threads.
PERMISSIONS
Governed agents
- Publish and use rights
AI governance decides who can publish or use each package and agent template, so not everyone can edit everything.
- Secrets stay in the vault
Packages refer to secrets in the vault. Values are not written into agent definitions or chat.
- Part of AI governance
Agent packages sit within AI governance, so security teams get permissions and an audit trail across the private catalogue.

Agents FAQ
An AI agent library is a private catalogue of reusable, versioned agent setups for your organisation. It shows what each agent includes and who owns it.
Packaging defines what goes into an agent and how it is set up. Orchestration runs multi-step or multi-agent workflows. Joyst handles packaging and the catalogue. It is not an orchestration platform.
Skills and MCP connections. The connection is an endpoint, not the credentials. The package can name a secret, but it does not store the secret’s value. It does not include prompts.
Yes. The catalogue holds one version of each setup, which you can use across harnesses and AI tools.
No. The library is private to your organisation. There is no public storefront for downloading agents.
Publish the package. A teammate’s tool can ask Joyst’s MCP for the setup steps. Those steps do not install the skills or connect third-party MCP servers by themselves. The tool follows the steps, including pulling skills and connecting to the endpoint.
