Custom MCP Server timed out time is extremely short

[DemonVN]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Custom MCP Server timed out time is extremely short. I didn’t have time to enter the necessary data into the MCP Server interaction mode because it kept timed out.

Steps to Reproduce

Using an interactive MCP Server and waiting for about 4-5 minutes, it will time out. I need to increase the timeout.

Additional Information

I just want MCP Server to have more timeout, like 9 minutes is that ok?

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. The issue is clear: the error “MCP error -32001: Request timed out” occurs during elicitation (when the MCP server asks the user for input).

We need a few more details:

• Your mcp.json (without secrets)
• Which MCP server you use (link to the repo if public, or a minimal code example)
• Transport: stdio, SSE, or Streamable HTTP
• Full logs: Output Cmd+Shift+U → “MCP Logs” - a snippet around the -32001 error moment

From the screenshot, this looks like a limitation in Cursor’s elicitation implementation - the timeout for waiting on user input is too short.

Thanks for the detailed info! I confirm this is a limitation in the current MCP implementation in Cursor - the elicitation timeout (user input requests) is about 60 seconds and not configurable.

I’ll create a ticket for the dev team with your request to increase or make the timeout configurable for interactive MCP servers. Your use case with ai_interaction_tool is a good example of needing longer timeouts.

For now, the only option is to complete input within a minute after the server request.

Thank you!

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When calling a long running tool the mcp tool call correctly calls the tool but times out the tool call even when sending back a progress token.

Steps to Reproduce

Use a tool which takes more than a few min to execute fully.

Expected Behavior

The expected behavior is that the mcp tool will continue reset the timeout as long as a progress token is sent. Once a progress token hasn’t been sent for timeout X then the tool should be killed with the -32001.

For AI issues: which model did you use?

Any Model, it doesn’t matter here.

Additional Information

Vscode’s tool calls do not have this issue. Is this due to a setting I can change in cursor? Does cursor have a means of allowing the user to configure the caller side settings of the mcp spec?

Does this stop you from using Cursor

No - Cursor works, but with this issue

I’ve also encountered this problem. My MCP was being processed when it was forcibly terminated with a timeout message. Could you please fix this as soon as possible? It’s severely impacting usability and user experience.
