Agent MCP servers expose your OpenAPI via MCP with all the performance benefits of Agent. Use your API in Cursor or any LLM in minutes, with preconfigured authentication and restricted access by default.

Big APIs blow past context limits with raw OpenAPI and still cost a lot with native MCP. Agent uses three fixed tools and fetches just-in-time details – so your agent uses 0.2% of the context window, fewer steps, and better routing. Benchmarks on Zoom and Notion included.

Learn how to spin up a spec-driven OpenAPI mock server with the Scalar CLI in seconds. We cover the key commands, practical workflows, and how the mock server helps teams build, test, and prototype in parallel.

Validate your OpenAPI document with the Scalar CLI before it breaks downstream tooling. This guide explains why validation matters, what errors to look for, and how Scalar handles validation under the hood.

A plain README can be good, but a dynamic one stands out. This post breaks down how we used SVG, foreignObject, CSS, and animation techniques to build a responsive, interactive GitHub README.

See how Scalar themes separate data, functionality, and presentation so teams can fully customize API documentation without rebuilding core behavior. We walk through the architecture and implementation details behind theming.

Cloudinary’s API-first strategy is a strong example of developer experience done right. We analyze what makes their API documentation effective and show how Scalar helps teams deliver a similar experience.

OpenAPI variables are powerful, but easy to confuse in practice. This introduction clarifies server variables vs parameters, when to use each, and how they shape a cleaner API description.

OpenAPI gives you a strong base, but product teams often need more. We share the Scalar-specific extensions we added (environments, code samples, internal endpoints, and more) and how we implemented them.

Security in OpenAPI can be confusing when multiple auth flows meet real-world API usage. This guide explains core security schemes, how they work in documentation, and how Scalar helps users authenticate correctly.

Drag and drop looks simple, but implementation details quickly get complex. We unpack the UX and engineering challenges we hit while building our own package, plus lessons learned along the way.

Our API docs sidebar became a major performance bottleneck at scale. This deep dive shows how we profiled the issue, redesigned the rendering approach, and achieved a 25x speedup.

.NET 9 introduces a new path for OpenAPI document generation, and Scalar completes the workflow with interactive API docs and testing. Learn how this pairing reduces documentation drift and improves API developer experience.

Scalar joined the OSS Pledge: paying open-source maintainers ($2,000+ per developer per year). We shared how much we give, who we support, and why it matters to us.
