Invalid schema for function #103

Description

@leogermani

I've seen this error for a few tools while setting up the MCP server on VSCode. I had to disable these tools in order to get it working:

  • mcp_wordpress-mcp_wc_add_product
  • mcp_wordpress-mcp_wc_update_product

Full error:

Sorry, your request failed. Please try again. Request id: 4f1c3e1a-ec13-4931-86e8-8514ebf46806

Reason: Request Failed: 400 {"error":{"message":"Invalid schema for function 'mcp_wordpress-mcp_wc_update_product': In context=('properties', 'meta_data', 'items', 'properties', 'value', 'type', '6'), array schema missing items.","code":"invalid_function_parameters"}}

I also got some " tool parameters array type must have items" errors described in #102
