Figma Devmode MCP doesn't work

Hi ​@welsewool, thanks for reaching out!
Could you share what error you’re seeing when it fails? even a quick screenshot or the error description can help us understand what might be going wrong.

In general, there are a few common reasons the MCP might not behave as expected.. here are some quick things to check:

1. Selection size - does the issue happen with all selection sizes? Can you try calling the MCP on a smaller selection and see if it behaves the same?

2. Figma <> IDE connection - can you make sure the MCP is still enabled in the Figma file you're working in, and that the tools are loading properly in your IDE?

3. Refresh both environments - Try refreshing Figma and restarting your IDE. That often helps resolve temporary sync issues.

4. Update Figma - Make sure you're running the latest version of the Figma desktop app.

Let us know if any of these helped, we’d be happy to help troubleshoot further!

Hi ​@Yarden K, 
I am trying to reach Figma via Cursor (which worked week ago) and currently I just receive that it’s a connection problem. 
I have tried all you mentioned - turning on / off, reinstalling, updating, different files, different sizes… Still no conversation between Cursor and Figma (but MCP is connected to it). 

I also tried in other IDEs and same issue. 

same problema with VS Code!

Same here I’m seeing 

{"jsonrpc":"2.0","error":{"code":-32001,"message":"Invalid sessionId"},"id":null}

Same problem. Claude code simply cant connect to Figma MCP. Figma, you are now a public company with billions in raised capital. Would you please fix your mcp server. this is such a pain.

{"jsonrpc":"2.0","error":{"code":-32001,"message":"Invalid sessionId"},"id":null}

Same problem, the SSE endpoint works, I don’t know where that is installed. I tried uninstalling Figma and install the latest and still the same issue.

I have been facing the same issue, when I try to ask cursor to access the Figma MCP it’s having connection issues. Any updates on how to fix this?
I’m getting the following message: 
MCP endpoint not available - Local server returns 404 for all endpoints

{"jsonrpc":"2.0","error":{"code":-32001,"message":"Invalid sessionId"},"id":null}

is there any update on this?

Figma customer service reached out to me directly after creating a ticket. They tried to help me troubleshoot but the best they could suggest was to keep both Cursor and Figma if both programs have the latest version.
I found a hack, I check in Cursor the MCP settings and if the Figma MCP is orange or red I just switch off the toggle and the switch it on again. Maybe try that it might work for you too.
