Description

While the initial scope of the official registry is of course MCP server-oriented, there is a (less pressing) need for similar functionality for MCP clients.

Accomplishing this would allow us to deprecate the manually managed list here.

Things to think through:

  • Does adding clients create issues for the core registry use case of being a server registry?
  • "client" vs. "host"
  • How should we model it in the OpenAPI spec?
  • Do we need some sort of client.json concept?
  • What implementation work needs to be done?

Research direction

Start by reviewing the registry's existing server model and OpenAPI specification, then compare them with the manually managed MCP client list linked in the issue. Define whether clients or hosts belong in the registry, how they should be represented, and what implementation scope follows before making changes.
