| Surface | Use it when | First success | Start here |
|---|---|---|---|
| TypeScript SDK | You are building a TypeScript application or service. | Authenticate, validate an example agreement, preflight deployment, and sign a deploy permit locally without deploying. | Quickstart with TypeScript SDK |
| MCP | You are connecting an AI agent or MCP-capable tool client. | Connect hosted MCP, call authenticated tools, validate an example agreement, and prepare deploy typed data. | Quickstart with MCP |
What happens after quickstart
Both paths converge at the same agreement lifecycle. After one quickstart succeeds, run Run an end-to-end agreement workflow to deploy an agreement, submit a signed lifecycle input, read state, and inspect input history.Where the TypeScript client reference fits
Use TypeScript client reference after first setup when you need constructor options, method details, signing helpers, diagnostics, path helpers, or exports. MCP users who do not already have signing infrastructure can also use the TypeScript SDK withviem as the local testnet signing harness for EIP-712 typed data returned by hosted MCP.
