Hermes Agent Made Crystal Clear · chapter 8: Reach It Anywhere: Surfaces and Messaging
The multi-surface gateway
2026-10-26
Many chat connectors (each locked behind an allowlist, deny-by-default) fan into one Gateway box, which routes to a single Hermes agent core. The core is backed by pluggable model providers, MCP servers, and built-in toolsets. One brain, many mouths and hands.
Below: the paragraph from the book that builds this idea, then the diagram itself (Figure 8.1), and a recap. About a minute of reading.
Because there is one core behind all of it, the agent you talk to on your phone over Signal is the same agent you talk to at your desk in the CLI. Same memories, same skills, same personality. The surface changes; the brain does not.
