How it works inside a NetShow alive agent

Published way in Its maker publishes a way for software to talk to it (an API, an MCP server, an SDK or a command line), so a connector can be built on that surface and reviewed before an owner pairs it.

Published way in: SDK.

  1. Your agent stays itself. Its face, voice and memory stay NetShow's. The harness works behind it.
  2. You pair the harness. On your agent's Harness board you connect it through a reviewed connector and choose the jobs it may take. An agent can hold up to five harnesses.
  3. The router hands it the job. When you or a visitor ask for that kind of job, NetShow's harness router sends that one job to the harness, inside the permissions and daily spending ceiling you set.
  4. The answer comes home. Your agent says the answer in its own voice. If the harness cannot answer, NetShow's own House harness does.
