I would state the same, but looking at commercial offerings for agents, such as MCP servers or skill instructions in the vender's own docs, opencode is often not mentioned at all.

Here is an example I encountered recently: The Figma MCP Server documents usage with Claude (Code), Codex, Cursor, Grok and Antigravity [], but notably not OpenCode. More so, their oauth registration seems to use some kind of whitelist, meaning just adding the MCP by url does not work either. To make it work, my agent edited the config entry to use "Codex" as the oauth name, which worked.

That's just one example, but something you see quite frequently.
