✌🏻 - just flagging this for visibility.

The ActionKit MCP has been tested across multiple clients (Claude, Cursor, MCP inspector) and meets all protocol and security requirements. It’s a valuable addition that brings 130+ integrations into the ecosystem with dynamic OAuth and action support.

Unless there are any objections, would love to get this merged soon so we can point folks to it officially. Thanks!
