When running a TaskMaster AI MCP server tool call and selecting to auto-approve a tool call, Roo gets an error and the tool call fails.

This could somehow be related to the MCP server itself, but I question why we interact with the MCP Server connection after selecting auto-approve checkbox. Maybe Roo tries to inject something into the stream of the MCP server when the Auto-Approve checkbox is clicked and it shouldn't if the tool is already running.

After auto-approve is set for a tool, it doesn't fail again. This is recreatable with the Taskmaster AI MCP server.

🔁 Steps to Reproduce

To reproduce:

1. an MCP tool has started (as indicated by "Running" status on the top of the tool call

• NOTE: Maybe it's clear already, but in order to be "Running" the user must select to approve the tool call manually

2. AND Tool call is not set to auto-approved already
3. AND the user then selects to Auto-Approve this tool call by clicking the checkbox in the tool call itself
4. THEN MCP connection fails with the error:
   Error executing MCP tool:MCP error -32000: Connection closed

After auto-approve is set for a tool, it doesn't fail again. This is recreatable with the Taskmaster AI MCP server.

💥 Outcome Summary

Expected the MCP call to work, but it fails. I suspect that we may try to inject something into the MCP server whenever the user clicks the AutoApprove checkbox and maybe it's an unhandled exception in the MCP server too, but Roo shouldn't send anything when the user selects the AutoApprove checkbox on an existing running tool call.
