> Each MCP server still needs to handle auth differently depending on what it's connecting to.

Setting aside expected criticism about this being some middleware layer, but we’ve launched a solution to this problem:

An MCP “SSO”, where you install and auth your MCP servers into profiles (collections of servers), which we virtualize into a single MCP server with only a single OAuth flow — simplifying the experience substantially for both the user of the MCP servers and the clients connecting to them.
