Composer 1.5 cannot see full response from Figma official MCP

[Mihai_Cracan]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When running “Get Design Context” using the official Figma plugin, it seems like Composer 1.5 cannot see the entire response somehow.

In the uploaded screenshot:

• image on the left: Composer 1.5 conversation
• image on the right: Sonnet 4.6 and Opus respectively

Steps to Reproduce

• install Cursor Figma official Plugin
• use model Composer 1.5
• give a Figma online link with a node selection
• ask model to retrieve the structure and styling
• model runs “Get Design Context” based on the installed Figma MCP

Expected Behavior

Should be able to see and use the full response, exactly as when using Sonnet 4.6 or Opus 4.6.

For AI issues: which model did you use?

Composer 1.5 → issue
Claude models → works

Does this stop you from using Cursor

No - Cursor works, but with this issue

P.S. In the actual Chat UI I can see that the Figma MCP actually returns the data, and is also visible in the UI, as you can see in the screenshot.

I tried with both Composer 1, and Composer 1.5 and they mention the cannot see it.

Opus 4.6, Sonnet 4.6, GPT 5.3 Codex → no issues

Hey, thanks for the detailed report.

It looks like this is a limitation of the Composer 1.5 model when handling large MCP tool responses. The data is clearly coming from the Figma MCP, you can see that in the UI, but Composer 1.5 seems to either truncate it or parse it incorrectly. Claude and GPT handle it fine.

For now, the best workaround for Figma related tasks is to switch to Sonnet 4.6, Opus 4.6, or GPT 5.3 Codex, which it looks like you are already using.

Could you grab the Request ID from the Composer 1.5 chat where this happened? Click the three dot menu in the top right of the chat, then Copy Request ID. That will help us investigate on the backend.

I will pass this to the team. Your report helps us prioritize this.

Hey Dean,

Already deleted the conversation from the Chat, but what you are explaining definitely makes sense. It seems aligned with the behaviour I encountered.

Would loved to still be able use Composer for this use-case too. It is of course not as intelligent as Opus, Sonnet or GPT, but the extra speed really helps stay focus on the work, compared to the other ones.
