Fireworks has introduced a new OpenAI-compatible Responses API with support for the Model Context Protocol (MCP), which is designed to connect large language models (LLMs) with proprietary APIs, tools, and data sources, solving the challenge of integrating these models into business operations. This open protocol facilitates seamless interaction between models and external systems, allowing developers to connect any model on Fireworks to a variety of tools, freeing them from vendor lock-in and enabling more flexible and powerful applications. The MCP handles the entire agentic loop—reasoning, tool selection, and execution—on the server side, simplifying the integration process and enabling rapid development of sophisticated applications. This innovation allows businesses to build applications such as e-commerce automation, internal operations bots, and data-driven assistants, all while maintaining control over their unique business logic and data connections. Fireworks encourages developers to explore this capability, which represents a step toward better-connected AI systems, and invites feedback on this preview feature.
