PRIVATE VS PUBLIC MCP REGISTRY
Private MCP registry vs public marketplace. Choose an allow-list.
Public MCP registries and marketplaces help people discover servers. Deciding what your organisation will allow is a separate task. Joyst is a private MCP registry for your organisation. Document, approve and govern the servers your team can use. It is an allow-list, not a storefront.
TWO KINDS OF REGISTRY
Public discovery vs private MCP registry allow-list
- Public registries
Public lists are built for browsing and discovery. They help with research, but they cannot record what your company allows.
- A private registry
A private MCP registry records which servers your organisation may use, who owns them and what has been approved.
- Connect, document, approve
Connect servers with care, document their tools and approve what agents and people may use. Governance and the audit trail sit alongside the catalogue.
PRIVATE MCP REGISTRY
What a private MCP registry means
- Your catalogue
Your organisation’s catalogue of connected servers, notes and approvals. Ownership and permissions stay with you.
- Notes beside each server
Notes live with each MCP server, so onboarding and reviews do not depend on old Slack threads or a forgotten wiki.
- Approve what the team can use
Approved servers are available to skills and agents. Servers that are not approved stay out of wider use.
- Govern and audit
Permissions and an audit trail, under AI governance, let security see who changed what.
PUBLIC LISTS STILL HELP
When public lists still help
- Use public lists for research
Public directories can help you find servers worth considering. They do not record what your organisation has approved.
- Bring approved choices into Joyst
Once a server is approved, Joyst adds it to your private MCP registry for the team to use.
- Feed agents from the private set
Skills and agents draw on the approved private catalogue, not on whatever someone bookmarked last week.
- No gateway today
Joyst does not offer an MCP gateway today. Start with the private catalogue to document, approve and govern the servers your organisation allows.
