MCP clients
Every MCP client, and what it actually supports.
The same MCP server doesn't behave the same everywhere. This is the 16 clients we track (MCP app rendering, tool-result images, display modes) from the catalog behind caniuse.dev, with how we know each fact.

Frequently asked questions
9 of the 16 clients in this directory render MCP apps: ChatGPT, Claude, Copilot, Cursor, Goose, MCPJam, Mistral, Slackbot, and VS Code. The rest can still call your tools and read your resources, but they will not draw an app's UI — so a server whose value lives in that UI shows those users nothing.
Because each client decides how much of MCP it implements: whether it renders an app's UI, which shapes of returned image the model can actually see, and which display modes exist. Your server sends the same response either way. What the user ends up seeing is the client's call, which is why this directory tracks it per client instead of assuming parity.
Open that client's page for what it supports, then run your server against MCPJam's emulation of it. The emulation applies that client's real constraints — app rendering, image handling, display modes — so you see the behavior your users would get without shipping first.
From the MCPJam host-compat catalog, the same data behind caniuse.dev. Provenance travels with every entry: 9 of these clients were probed directly, and the other 7 are marked on their own page as vendor-documented or assumed. The catalog was last reviewed 2026-07-08.
