Best AI SDKs for Grok Bot

21st is a development platform designed to help engineers quickly build and deploy AI agents inside their applications. The platform provides a specialized SDK that simplifies the process of defining agent behavior, integrating tools, and connecting AI models. Developers can create agents using familiar technologies such as Next.js, React, TypeScript, Python, and Node.js, making integration straightforward for modern applications. Once an agent is defined, the platform allows it to be deployed with a single command while automatically handling infrastructure requirements. 21st provides sandboxed execution environments through E2B sessions, ensuring that agent operations run securely and independently. The platform includes a ready-to-use chat interface component that can be embedded directly into an app for user interaction. Additional features include token streaming, conversation history, tool execution, and built-in observability for debugging and monitoring. Developers can replay sessions and trace tool calls to better understand how agents behave during execution. The system also supports spend limits, authentication controls, and rate limiting to manage AI usage across users. By combining development tools with managed infrastructure, 21st helps teams launch scalable AI agents without building complex backend systems.

Manufact serves as a comprehensive platform designed for the creation and deployment of MCP applications and servers, providing teams with expedited access to the ChatGPT Apps Store, Claude Connectors, and various user-agent interaction points. The mcp-use SDK functions as a complete MCP framework, facilitating the development of MCP applications for both ChatGPT and Claude, along with MCP servers tailored for AI agents. With Manufact, every phase of the MCP lifecycle is streamlined without the need for additional tools: developers can create using an SDK, a skill, or a vibe; initiate deployment with a single command; publish by following marketplace guidelines and utilizing auto-generated submission resources; refine their products through Cloud Inspector; and oversee performance with features like analytics, session replays, trace logs, error metrics, and notifications. Teams benefit from the flexibility to scaffold with the MCP-use SDK, integrate a skill into a coding agent, outline an app and observe the scaffolding process, or seamlessly incorporate an existing MCP server without modifications. Moreover, Manufact Cloud establishes a connection to a repository just once, ensuring that every push leads to automatic deployment, while providing preview URLs for pull requests, as well as managing custom domain setups and SSL certificates. This all-in-one solution enables teams to focus more on innovation rather than the complexities of infrastructure management.
