Walkthrough

The change updates the callTool function in the McpManager class to ensure that the arguments property passed to client.callTool is never undefined. If parsedArgs is undefined, an empty object is provided instead.

Changes

File(s)	Change Summary
src/core/mcp/mcpManager.ts	Updated callTool so that arguments is always an object, defaulting to {} if parsedArgs is undefined.

Poem

A tweak in the code, so small and neat,
Ensures no undefined sneaks in on fleet.
Arguments now always have a face,
An empty object, just in case.
Hopping forward, bugs retreat!

396-397: Good fix to ensure arguments is never undefined.

This change properly handles cases where no parameters are provided to REST API calls by using an empty object as a fallback when parsedArgs is undefined. This avoids potential errors when making tool calls without parameters.
