Platform MCP tool results now render as cards in clients that support MCP Apps, such as ChatGPT: a read shows the resource, a list shows a count and the first few rows, a change shows what was done, and every card links straight to the matching dashboard page. Browsing the catalog gets the same treatment, with search results rendering as a carousel of server cards you can add to your project without leaving the chat. ChatGPT connections also now get the full Platform MCP toolset directly, since the app directory requires each operation to be its own tool rather than routed through a search-and-call pair. More on this in Platform MCP and the MCP catalog.

Features

• Platform MCP tool results now show as cards in MCP Apps clients #8794 - A tool call now returns a card for results you'd otherwise open in the dashboard: an MCP server, plugin, skill, risk policy, gateway, or dashboard. A refused or unavailable call shows the reason with a request-access link when one exists. Clients without MCP Apps, and the managed assistant, see the same results as before. (Author: @adaam2)
• Catalog search results now show as a card carousel #8791 - Searching the MCP catalog from an MCP Apps client now returns a carousel of server cards with the logo, name, and description. A server not yet in your project shows Add to project; one already there shows Open, linking straight to its dashboard page. (Author: @adaam2)
• ChatGPT connections now get every Platform MCP tool directly #8799 - ChatGPT now always lists the full Platform MCP toolset, narrowed by the existing ChatGPT allowlist, instead of the search, describe, and call tools other clients use to run tools by name, since the ChatGPT app directory requires each operation to be its own tool.

• Platform MCP ships a sign-in skill for clients that skip the OAuth prompt #8772 - When Platform tools are missing or a call fails with an authentication error, a bundled platform-sign-in skill now walks you through signing in for your client, including codex mcp login platform for Codex, which doesn't open the sign-in page for plugin MCP servers on its own.

Bug fixes

• Connect on a Platform MCP server card now opens the sign-in page directly #8777 - Connect now takes you straight to the provider instead of the server's Settings page, and the card shows the catalog name and logo, such as "Linear." (Author: @adaam2)
• The Platform MCP plugin is now listed as "Speakeasy Platform" #8844 - Claude, Cursor, and Codex marketplaces now list the plugin as "Speakeasy Platform." The underlying plugin name speakeasy and MCP server name platform are unchanged, so existing installs keep working. The Claude plugin also now ships a listing icon (#8845) and links to Speakeasy's privacy policy from its manifest (#8843). (Author: @adaam2)
