FastMCP

Built by the creators of FastMCP

FastMCP is the most widely used MCP server framework in any language, with 80.1M+ downloads last month. Horizon Registry is the enterprise MCP registry from the team that helped define how modern MCP servers get built.

MCP Server Sprawl
Is Already Happening

A GitHub MCP server here. A Jira server there. Someone builds a Slack integration. Then a Salesforce connector. Then ten more.

Then someone forks one. Then nobody remembers which version has the security patch. Then an agent uses the wrong one to access customer data.

Public directories help you discover what exists. But your organization still needs to know which servers are approved, who owns them, and which version is safe for production.

That's what a private MCP registry solves.

MCP Server Catalog

Find, approve, and manage every MCP server in one place

Discover what's available

Search MCP servers by name, capability, or connected system, from GitHub and Jira to Slack, Salesforce, databases, and more.

Know who owns what

Every MCP server has a designated owner. Know who built it, who maintains it, and who to contact when a team needs access or a capability needs to change.

See every tool and capability

Browse the tools, resources, and prompts each MCP server exposes. Understand what an agent will actually touch before you approve it for production.

Control which versions are approved

Pin approved versions for production use, flag deprecated servers, and keep every team on the version security and platform teams actually want in use.

Remix Servers

Compose the exact MCP server each team needs

Your engineering team needs GitHub, Jira, and PagerDuty, but not Salesforce. Your sales team needs Salesforce and HubSpot, but not production databases.

Remix servers let you combine tools from any MCP server, first-party or third-party, into a single purpose-built endpoint. One Engineering Assistant server with the right tools for incident response. One Sales Ops server with the exact systems needed for account work.

Engineering Assistant

GitHub + Jira + PagerDuty for triage, release checks, and incident workflows.

Sales Ops

Salesforce + HubSpot for pipeline updates, account context, and CRM cleanup.

No over-provisioning. No context pollution. No agent accessing tools it shouldn't.

Build the server in Deploy, register it here, and enforce access through Gateway.
