🐛 Bug Fix

[vercel]

@mubashir1osmani is attempting to deploy a commit to the CLERKIEAI Team on Vercel.

A member of the Team first needs to authorize it.

@mubashir1osmani can you explain the issue + the fix?

[mubashir1osmani]

@krrishdholakia mcp servers when used with auth token / api key returned tools list.

mcp-server/tool/call endpoint returned a 401 because the auth headers were sent properly (i.e x-mcp-servername-authorization & litellm api key)

can you test in staging ?
