With the configuration

"confluent-cloud-global-server": {
"type": "http",
"url": "https://api.confluent.cloud/mcp/v1",
"headers": {
"Authorization": "Basic ${env:CONFLUENT_ENCODED_CREDENTIALS}"
}
},

Current vs. Expected behavior

I expected to interact with MCP Global Server but got and error as seen in "Relevant log output"

Probably the output should have Items

{
"type": "array",
"items": { "type": "string" }
}

and not just
{
"type": "array"
}

Relevant log output

Failed to validate tool mcp_cc-mcp-servic_get_connector_logs: 
Error: tool parameters array type must have items.
