Requests and responses

The TypeScript SDK accepts a string or structured input in thread.run() and returns a turn result. runStreamed() returns an async generator of structured events.

The MCP server speaks JSON-RPC 2.0 over line-delimited stdio. An MCP client must initialize once per connection, send initialized, then call methods. Requests and notifications use the exact schemas in the MCP interface.

Do not parse human-readable CLI output when the SDK or MCP interface provides structured data.
