Claude is flipping one Wisesheets URL letter from lowercase to uppercase

### What happened?

When I paste the url into the connector form, the "k" is posted as "K".
https://mcp.wisesheets.io/v1/mcp?apiKey="MY KEY"
I have made a few attempts with the same result. Any suggestions would be appreciated.
Thanks.

### What did you expect to happen?

the correct Wisesheets URL is:
https://mcp.wisesheets.io/v1/mcp?apikey="MY KEY"
The "k" in apikey must be lowercase.

### Steps to reproduce
