Adding targets to an existing gateway

After Creating gateways, you can add targets which define the tools that your gateway will host. Gateway supports multiple target types including Lambda functions and API specifications (either OpenAPI schemas or Smithy models). Gateway allows you to attach multiple targets to a Gateway and you can change the targets / tools attached to a gateway at any point. Each target can have its own credential provider attached enabling you to securely access targets whether they need IAM, API Key, or OAuth credentials. Note: the authorization grant flow (three-legged OAuth) is not supported as a target credential type.

With this, Gateway becomes a single MCP URL enabling access to all of the relevant tools for an agent across myriad APIs. Let’s dive deeper into how to define each of the target types.
