Invalid schema for function

[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

Hello,

i had the same problem, and i fixed it by just generating new JWT token and updating my mcp.json (mcp.json is what vscode has, for cursor or claude it will probably be different)

idk how it fixed it, the error message is bizarre...

please try this and report how it went :)
