If there's a standard instead of needing to download the Jira mcp server, you just visit their website and all the tools are described and usable from there.

Or put differently, as a company / group / individual, instead of needing to build and distribute an mcp server and public API, you can just support WebMCP.

Another alternative is LLMs / agents operating playwright or the equivalent which will likely be less reliable and consume more tokens. (By a fair margin)
