Describe the issue
When attempting to connect the Snowflake MCP integration, the OAuth authorization flow fails with two issues:
The OAuth URL is missing /oauth in the path - Claude redirects to /authorize instead of /oauth/authorize, resulting in a 404 error
The scope parameter is set to scope=claudeai, which Snowflake does not recognize, resulting in "The requested scope is invalid" error
