HuskyLens V2 MCP error when connecting to Cherry Studio
Solaria 2026-04-24 06:10:09 737 Views3 Replies When I connect HuskyLens MCP to Cherry Studio, I get the following error when it tries to validate the tools:

It complains about an invalid “int” value type. Looking through the tool definitions, looks like it's the “multi_algorithm_control” tool:

…it's got two “int[]” fields. Disabling that tool removes the error and allows the request to succeed.
ChatGPT summarizes it like this:
Problem:
The tool defines parameters using non-standard types such as:
"int"
"int[]"
These are not valid JSON Schema types.
Expected (per JSON Schema spec):
"integer" instead of "int"
arrays must be defined as:
{
"type": "array",
"items": { "type": "integer" }
}
Impact:
Causes strict MCP clients (e.g., Cherry Studio) to fail during tool validation
Results in runtime error:
"invalid 'int' types in function declarations"
Workaround:
Disabling the tool allows normal operation
Request:
Update MCP schema to conform to JSON Schema standard
Thanks so much for your detailed and helpful feedback! I didn't catch this issue earlier as I tested with other models. We'll fix this JSON Schema compatibility problem in the next firmware update, please keep an eye on the firmware release notes on our Wiki!
Yx Hi, please check your hardware firmware version. If it isn't the latest 1.2.2, follow the tutorial to update it to the newest firmware. Link: https://wiki.dfrobot.com/sen0638/docs/22673
The MCP tool parameters on my end are shown as: 
Yx The firmware is up-to-date:

The data types are as indicated: “int[]”
Is this v1.0.1 of the MCP server? →

Cherry Studio is v1.9.4
