Built for agents

Tools an autonomous agent can actually be trusted with.

Every server we ship is build-only and keyless by default: reads run against public endpoints with no credentials, and writes come back as unsigned transactions for you to inspect and sign yourself. The agent can construct the work. It cannot move your money.
