One of the most fun projects I've had the pleasure of working on. Please check out the research blog post we just put up!

Auto-review is now the default for all new users.
A classifier subagent reviews actions in context before deciding whether to allow, block, or ask for approval.
Our evals show it's 97% accurate, with most misses near ambiguous edges.

We recently shipped quality-of-life improvements to the Cursor CLI to make working with agents in the terminal more delightful.
Use /debug to find root causes and fix tricky bugs that are hard to reproduce or understand.

Claude Opus 4.7 is now available in Cursor. We've found it to be impressively autonomous and more creative in its reasoning.
We're launching it with 50% off for a limited time. Enjoy!

Cursor now shows you demos, not diffs.
Agents can use the software they build and send you videos of their work.

This can be a completely made-up endpoint. In fact, any random prefix will yield the same outcome. This is done to prevent endpoint enumeration attacks. That said, it is still possible that this connection string appeared in the model’s training data

claude code just tried connecting to someone else's database (!!!)
it used my password, but on a random neon aws db
I tried connect to that database (ep-white-lake-a______v-pooler.us-east-2. aws. neon. tech) via psql, and it actually exists!
and no, that's not mine, i never used neon before, not even on another repo on my laptop (afaik)
if .envs are leaking data via llm's we are cooked
I asked why it did that, and it said it hallucinated - but from a real URL. imagine if the pwd was actually valid?!
for @AnthropicAI @claudeai: this is claude code Version: 2.0.76, Login method: Claude Max Account, Model: Default Opus 4.5, IDE: Installed VS Code extension (Windsurf)

The Neon Data API is here, a PostgREST-compatible REST API for Postgres.
Behind the scenes, we reimplemented PostgREST in Rust and integrated it into the Neon platform so it’s leaner, multi-tenant, and scales to tens of thousands of databases 🧵

"Your API is not an MCP." - Learn from David Gomes why designing your MCP toolkit takes more than just exposing an API.
@davidgomes leads the development of Neon's MCP server and shared key lessons at Microsoft Build 2025. Watch the talk here: build.microsoft.com/en-US/se…
