Also in this newsletter: An Arazzo primer, MCP and OpenAPI, and a Hono deep-dive - Author: Alexander Karan - Tags: 📰 APIs You Won't Hate (The newsletter) API's are once again having their moment in the sun; people don't just want to go to a web app; they want your data to plug into an MCP or this graph or that connector. OpenAPI specs and design-first are also being dragged front and centre. Well-defined relationships and good documentation are a focal point when Agents get involved. The interesting trend I am seeing is the push to do insights and aggregations inside the API so they can be tested and validated, rather than letting Agents draw their own conclusions. I've suddenly found time-series and statistical APIs a focus point. While I find the negative effects of AI often overwhelming, I do enjoy the push for better, more complete APIs. \-- Alexander --- ## The API Roundup *API News, links, and tools from around the web* ### [Use Arazzo ](https://apisyouwonthate.com/newsletter/throwaway-tooling/) A JaveScript/TypeScript toolkit for Arazzo. It lets you validate documents and run workflows against live APIs. It has a great CLI and an MCP compiler on the roadmap. If you're still unsure what Arazzo is, we've got you covered with a nice [intro blog](https://apisyouwonthate.com/blog/introducing-arazzo-describe-api-workflows/). ### [Karve, a native Windows workspace for your .http files](https://karve.dev/?utm%5Fsource=apisyouwonthate&utm%5Fmedium=newsletter&utm%5Fcampaign=classified) Karve gathers the .http files scattered across your repos into one native Windows workspace without moving them. Run requests and inspect responses without opening an IDE. There’s a 15-day free trial, and if you keep it, you pay once. `sponsored` ### [MCP Is The New REST](https://www.youtube.com/watch?v=4EK3usamWOc&list=PLGZGLmEvGK8I&index=9&ref=apisyouwonthate.com) Like I said in the intro API's are having a new moment in the sun, in part due to MCP, but is wrapping your API in MCP the right way? Andy put together a great talk at GopherCon about what MCP is and how TypeFrom is looking beyond REST as MCP becomes the new integration surface. Plus, it has Back to the Future memes. What more could you ask for? ### [A Deep Dive Into Hono](https://flaviocopes.com/how-hono-is-built/?ref=frontenddogma.com) Hono is a lightweight web framework built on web standards. Honestly, one of my favourites when building on Cloudflare. Check out this awesome post on how a request runs through Hono via routing, middleware, context, web standards, and runtime adapters. The quote at the start really sticks with me: > I like frameworks that disappear when I look closely at them ### [OpenAPI React Query Codegen](https://socket.dev/blog/openapi-react-query-codegen-npm-compromise?ref=apisyouwonthate.com) A codegen tool for turning OpenAPI specs into React Query code was hit with a supply chain attack. Socket has a great write-up covering the ten compromised versions that were published. Maybe we should go back to building every inch of our software ourselves to avoid security issues 😂. ### [FastAPI Conf '26](https://fastapiconf.com/?ref=apisyouwonthate.com) The FastAPI Conf is coming to Amsterdam this October (honestly the best month of the year). You can still get your tickets now, with great speakers from Google DeepMind, OpenAI, and my favorite Space Telescope Science Institute. Who doesn't like space and telescopes....? --- ## APIs You Won't Hate *The latest from the team at API's You Won't Hate.* ### Join us on the Podcast We are lining up the next series of APIs You Won't Hate (the [podcast](https://apisyouwonthate.com/tag/podcast/)) - and we're looking for guests! If you (or someone you know) is working on an interesting API project, product, or initiative, [drop us a line](mailto:mike@apisyouwonthate.com). --- ## From the Community *Articles written and shared in our free* [*Slack community*](https://slack.apisyouwonthate.com/?ref=apisyouwonthate.com)*.* ### [Can MCP Server Finally Get Their Own OpenAPI](https://apichangelog.substack.com/p/can-mcp-servers-finally-get-their-own-openapi) What does an MCP server do? You don't know until you connect and run a command. Maybe it's time they get their own documentation standard. Bruno is trying out [mcpdesc](https://mcpdesc.org/?ref=apisyouwonthate.com) and explains why. ## Support APIs You Won't Hate When you become an member, you'll get access to members-only content while directly supporting our work.
