Description
This happens in both http and stdio type mode for ai game developer mcp.
I was using SWE 1.6 model here. The same problem happens with different model chosen like Kimi K2.5
Used other - custom option since windsurf isn't in the list in MCP configuration
Got this result in both linux desktop ( nobara ) and macboook arm macos
This error doesn't happen when other MCPs were used, like one from coplay, etc.

Research direction
Start by reproducing the invalid-arguments error with the AI Game Developer MCP through Windsurf in both HTTP and stdio modes, using the SWE 1.6 and Kimi K2.5 models. Compare the result with another MCP integration; done means tool calls succeed without the reported error on Linux and macOS.
