Patent PreCheck

What it does

You built something clever with Cursor or Claude. Will it survive a patent examiner? Patent PreCheck is a free, keyless patentability read on your code in about 60 seconds: USPTO pillar scores (eligibility, novelty, nonobviousness), prior art matches, and the pillar holding you back. Web app, hosted MCP at patentprecheck.com/mcp, or npx in CI. Triage before counsel. Not legal advice.

Before you spend $10,000, find out if your idea is already patented. Free prior-art screen with a proceed / caution / stop verdict — then Interactive Code Review and Filing Packet when you are ready.

Patent PreCheck evaluates your invention against existing prior art, assesses it against the criteria an examiner will actually apply, and identifies what needs to be improved — or advises you not to file at all. Many tools will sell you a patent application for an idea that was already patented in 2019. We won’t. Novelty read, closest references, plain-English overlap, and a proceed / caution / stop verdict. Free. §101, enablement, claim breadth, obviousness exposure — every weakness with a specific fix, not “add more detail.” Disclosure-specific monitoring while your application is pending. Quiet weeks stay quiet. Screen free → Interactive Code Review $69.95…from patentprecheck.com

  Hey HN, I’m Yannis, co-founder of Preloop. We’ve built a proxy for the Model Context Protocol (MCP) that lets you add human approval gates to your AI agents without changing your agent code. We’re building agents that use tools (Claude Desktop, Cursor, etc.), but we were terrified to give them write-access to sensitive systems (Stripe, Prod DBs, AWS). We didn't want to rewrite our agents to wrap every tool call in complex "ask_user" logic, especially since we use different agent runtimes. We built Preloop as a middleware layer. It acts as a standard MCP server proxy.You point your agent to…

  Free local security checks for AI coding in VSCode, Cursor and Windsurf2025 · ▲43

  Hi HN! We just launched Codacy Guardrails, an IDE extension with a CLI for code analysis and MCP server that enforces security & quality rules on AI-generated code in real-time. It hooks into AI coding assistants (like VS Code Agent Mode, Cursor, Windsurf), silently scanning and fixing AI-suggested code that has vulnerabilities or violates your coding standards, while the code it’s being generated. We built this because coding agents can be a double-edged sword. They do boost productivity, but can easily introduce insecure or non-compliant code. One recent research team at NYU found that 40%…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
