Integration Ecosystem

Add Stacksona to the agent tools and workflow platforms your team already uses. Choose the runtime your agents use and see where to request approval before an action runs.

Start with the SDK, MCP server, n8n node, or the framework guide that matches your stack. Each path shows where Gate belongs before the agent sends, updates, exports, refunds, or calls a production system.

Live npm tools

Installable developer surfaces

Use the official Stacksona packages when you want a maintained entry point instead of hand-rolling the Gate API integration.
