Designing APIs for agents
The New Stack Yan Xie
Webflow redesigned its MCP server throughout 2025 to make APIs work better for AI agents rather than humans, moving from low-level developer endpoints to task-oriented tools that reduce multi-step orchestration. The company built the MCP server on Cloudflare Durable Objects to manage stateful sessions and support both headless operations and browser-based Designer actions, with tool surfaces organized into layered domain tools and actions. Agent-optimized APIs now prioritize execution reliability, clearer error guidance, and intent-driven operations over developer flexibility, with Webflow exploring filesystem abstractions and code-oriented environments as long-term solutions to reduce discovery overhead as product capabilities expand.
Why it matters
In early 2025, Webflow started building for MCP before there was a clear playbook for agent-ready APIs. We publicly announced The post Designing APIs for agents appeared first on The New Stack.
