Integrations let your agent take actions—not just answer questions.

​
Server-Side Tools

These are tools that run on a server. The agent calls them, they execute, and results come back.
Start with Envoy if you don’t have an MCP server yet. It reads your code and generates one for you.

​
Client-Side Tools

Tools that run in the user’s browser. The agent calls them, the widget executes them locally.

​
External MCP Servers

Third-party MCP servers that you connect to (not your own backend).

​
Example Actions

Server-Side (OpenAPI or MCP):
  • Check order status
  • Create support tickets
