With Fusion & HotChocolate 16, we're launching a new MCP adapter to expose GraphQL operations as MCP tools. We're also adding support for the MCP Apps standard for building agentic UI components. Check out the latest post for all the details: chillicream.com/blog/2026/05/2…
AI agents can call APIs, but can they actually understand them? @Pascal_Senn shows why #GraphQL is such a strong fit for agents when using semantic introspection for huge production schemas. This one is worth watching 👇 youtu.be/2Ud1gxUpgrY
@michael_staib and me will be at GraphQL Day in Amsterdam on June 9th and 10th. We still have a few free tickets for you! Send me a DM if you are interested. See you there! Find out more: graphql.org/day/2026/amste…
@StatisticsFTW @cnakazawa yes - but thats a backend problem... graphql and its patterns make a lot of sense on the client, but i'd argue you get even more benefits when you have a graphql backend. especially when client and backend talk the same language..
@cnakazawa sure - i meant more that the concept of fragments and composition is part of the graphql query language and this is leveraged by relay, apollo client, urql etc.
@cnakazawa i see - already sending this through to folks that never got to experience relay so they can finally know what i am talking about 😅 so you'd say - fate partially solves a problem on a client that graphql solves higher up in the stack?
@cnakazawa So essentially: just because the backend does not provide a GraphQL interface? also, I've read through the docs and I like fate, dont get me wrong.
Wrapping up another great API Days. Looking forward to seeing everyone next week at GraphQL Conf in California - registration is still open and free to attend. graphql.org/conf/2026/
GraphQL wasn’t made for AI. But it might be one of the best ways to talk to it. chillicream.com/blog/2026/04/2…
Clauding (verb) — Relentlessly hammering prompts into Claude with zero strategy and full confidence. You don’t understand the output. Claude doesn’t understand the input. But eventually, somehow, it works. #Claude
Keynote Speaker: “AI is revolutionizing healthcare research and will help us defeat cancer. At scale. Very soon.” Meanwhile, Engineers (prompt to ChatGPT): “Give me 5 better names for the variable _aggregatedContextualConfigurationOverrideValue.”
🔥 Modern enterprises don’t have to be disconnected islands. See how agentic platforms turn silos into collaboration and intelligence at #GraphQL Day Paris graphql.day Catch the talk: From Isolated Services to Agentic Platforms - @michael_staib & @pascal_senn #AI
Congrats to @martinbonnin and @Pascal_Senn for being elected into the GraphQL TSC! graphql.org/blog/2025-02-0…
This week's #graphqlstar is the one and only @Pascal_Senn 🎉 Pascal has been an important contributor to the composite schema WG, website, and of course the spec! Thank you, Pascal!

I think it's beautiful that competitors in an ecosystem can come together to build a standard that is free for everyone to use and find common ground. The composite schema specification unifies all the best parts of existing federation solutions! 🌐✨
I really enjoyed working on the composite schema specification and am excited to push the boundaries of distributed GraphQL together with @theguilddev and @apollographql and all the others involved!
#GraphQLConf has come to an end, and what a fantastic conference it was! It was wonderful to finally meet in person all the amazing people I've been working with over the past year.
