Definition
A tool gateway is a shared service that sits in front of an agent's external tools to centralize authentication, rate limiting, caching, and observability across agent calls.
In Depth
As agent fleets grow, managing credentials and rate limits per agent becomes intractable. A tool gateway consolidates that layer: the agent calls the gateway, the gateway handles auth to the downstream tool, and usage metrics land in one place. Hermes Agent and several internal enterprise harnesses shipped tool-gateway patterns in 2026. Scavio integrates cleanly behind a gateway because its credentials are a single header and its responses are cache-friendly.
Example Usage
The platform team stood up a tool gateway so their 30-agent fleet could share a single Scavio API key without each agent managing secrets.
Platforms
Tool Gateway is relevant across the following platforms, all accessible through Scavio's unified API:
- Amazon
- YouTube
