THEN Apply a type assertion to explicitly type the return value's content as an array of content block objects (e.g., `{content: Array<{type: string, text?: string}>}`) until you can upgrade to an SDK version that includes the type fix. Alternatively, check that you are using a recent version of the SDK where this issue has been resolved.

const callToolRet = await client.callTool({ name: 'a' }) as { content: Array<{ type: string; text?: string }> }; if (callToolRet.content.length && callToolRet.content[0].type === 'text') { return callToolRet.content[0].text; }
