Issue with MCP's with Claude

Hi - One thing we were trying to use AP for was creating MCP’s to then add to Claude Web, since Claude Web custom MCP connectors can be used by Claude’s app in the Slack marketplace so we can effectively use any MCP in Slack. The problem is there’s no other auth mechanisms besides OAuth, and AP has a different Auth method. Is there a way we can figure our AP MCP’s in Claude web via these inputs or any workarounds?
