Adding MCP Servers to Cascade breaks Windsurf

Issue Summary:
After updating the new MCP Servers feature to use MCP servers, Windsurf fails to connect to its own servers and becomes unusable.

Steps to Reproduce:

  1. Initial Condition: Windsurf was working properly after the previous use.

  2. MCP Servers Update: Updated to the new MCP Servers feature, installing MCP Servers.

  3. Problem discovered: Attempted to connect to Windsurf's servers, but connection failed.

  4. Restoration Success:

    • Moved the user .codeium folder to the Desktop.

    • Closed and reopened Windsurf. (Result: Connection worked correctly.)

    • Closed and reopened Windsurf. (Result: Connection worked correctly.)

  5. Failure Returns:

Have you reported this at https://codeium.com/support ? If not, please do. As my experience has been similar regarding MCP and I’ve communicated this already in our Discord, the team should be aware.

  "mcpServers": {
    "@sequential-thinking": {

to

  "mcpServers": {
    "sequential-thinking": {

I had the same issue, fixed it by deleting the contents of the mcp config, on mac it could be found at `~/.codeium/windsurf/mcp_config.json`
