Learn how to use pre-built provider-hosted MCP servers

The fastest way to get started is by connecting to existing MCP servers provided directly by SaaS providers that offer them.

MCPs with OAuth 2.1/PKCE support

These servers often implement OAuth 2.1 with PKCE for secure authentication that allow for 1-click authentication without the need for API keys.

Here's an example list of popular service-maintained MCP Servers that support 1-click install via the OAuth 2.1/PKCE authentication flow.
