MCP Management API Issue: Content Type Creation Serialization Error

Core Issue

The create_content_types function in the xperience-management-api MCP server fails with a serialization error when attempting to create content types. The error indicates the tool receives a string instead of an object, despite passing a properly structured data object.

Error Message

Error calling tool: Parameter 'data' must be one of types [object, object], got string
