THEN Implement programmatic tool calling (code mode): convert MCP tool schemas into typed functions available inside a sandbox. Let the model write a script that calls multiple tools and returns only the final result. This avoids round-trips through the model for each intermediate result, reducing token usage and latency.

// Auto-generated from the Logging MCP server's tool schema
interface LogEntry {
  timestamp: string;
  message: string;
  level: string;
}

function logging_getLogs(input: {
  level: "error" | "warn" | "info";
  since: number;
}): Promise<{ entries: LogEntry[] }> {
  return mcp.callTool<{ entries: LogEntry[] }>("logging_getLogs", input);
}

// Auto-generated from the Ticketing MCP server's tool schema
function ticketing_createIssue(input: {
  title: string;
  body?: string;
  priority: "low" | "medium" | "high";
}): Promise<{ issueId: string }> {
  return mcp.callTool<{ issueId: string }>("ticketing_createIssue", input);
}
