Cannot pass an integer correctly

[neominik]

Describe the bug
Currently, fields that are specified as type integer will result in a text field being displayed and a string being passed to the MCP server, which is not compliant to the JSON schema spec. The number type seems to be supported.

To Reproduce
Steps to reproduce the behavior:

1. Create an MCP server that has a field of type integer somewhere in the inputSchema
2. Try to pass an integer in the inspector
3. Observe that a string has been passed

Expected behavior
Only integers that are valid according to the JSON schema spec can and will be passed to integer fields.

Logs
N/A

Working on testing this in this branch, if you also want to verify it addresses the issue: #156

Hello @olaservo

I notice the input handling change has been merged in #159 but I'm wondering if it has been released yet? The latest version seems to be v0.6.0, but in that version I seem to be unable to pass and Integer to an integer field. I'm certinly typing a number into the box and that field accepts and integer, so I'm guessing your fix is not in 0.6.0.

Hi @gerrywastaken yes you're correct - I don't have permissions to publish a new version of the npm package, I'll ping the admin group to bump the package and publish it to a new version so we can get the latest fixes through npm/npx.

Thank you. I appreciate it!

[olaservo]

@gerrywastaken BTW the latest version 0.7.0 was just published.

@olaservo Thank you! I just tested and it seems integers may not yet be working though.

@gerrywastaken darn I must be missing something in the way I was trying to test for this here: https://github.com/modelcontextprotocol/inspector/blob/main/client/src/components/__tests__/DynamicJsonForm.test.tsx#L40

Could you share the server that you're using so I can make sure I'm reproducing this correctly?
