Supabase MCP repeatedly fails when used with Claude Desktop

[SidKaljeKumo]

Bug report

Describe the bug

Claude desktop fails to work with supabase. Although it works for a couple requests upon first connection, it stops working after that. Reloading and quitting doesn't work, nor does replacing your PAT and double-triple checking your project ID. However, it seems to work perfectly on other MCP testers, like MCP Inspector v0.16.5.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

Try Supabase MCP on Claude as is indicated on the website.
