If you build with MCPs, this one is worth reading.

(bookmark it)

The paper covers five recurring MCP server patterns across fifteen independently developed servers.

That taxonomy is useful because I see many AI teams rebuilding the same shapes without shared names.

If you are building MCP servers, this is a practical reference for deciding whether your server is exposing resources, orchestrating tools, managing sessions, aggregating proxies, or adapting a domain workflow.
