localharness is one Rust crate that is both an agent SDK and a wallet-owning, self-sovereign agent.
The SDK provides streaming, tool calling, hooks, policies, triggers, and MCP behind a single Connection seam. The CLI runs an agent whose identity is an on-chain name with its own wallet, so agents can discover and pay each other. It also serves your agent over the Agent Client Protocol (ACP) for Zed, JetBrains, and other ACP clients via localharness acp.
