Software for Agents @aaron_epstein The next trillion users on the internet won't be people. They'll be AI agents, and they're already doing real work on top of software that was designed for humans clicking buttons. Every major category of software needs to be rebuilt for agents as first-class citizens, and that won't come from incumbents.

"Make something agents want"

Your UI is my opportunity, to paraphrase Jeff Bezos. - YC Startups, Summer 2026 If you’re still building for humans, your product is on notice. You need to start making what agents want: APIs, CLI, MCP and Skills. See ycombinator.com/rfs#software… by @aaron_epstein

Welcome Salesforce Headless 360: No Browser Required! Our API is the UI. Entire Salesforce & Agentforce & Slack platforms are now exposed as APIs, MCP, & CLI. All AI agents can access data, workflows, and tasks directly in Slack, Voice, or anywhere else with Salesforce Headless 360. Faster builds, agentic everything. 🚀 #Salesforce #Agentforce #AI venturebeat.com/ai/salesforc…

Apps inside ChatGPT are the way to get your business discovered by 900M people using it, but building them is still too hard. So we built Fractal: @Lovable for ChatGPT Apps It’s the fastest way for business owners, with or without a technical team, to ship exceptional ChatGPT apps

agents are the software market from now on build something agents choose cli/api first

I suspect we’ll start to see a Darwinian effect in software where the products without the comprehensive APIs or CLIs will just slowly die off. The forces are just too strong on this one.

💯 "If you build it, they will come." :) ~Every business you go to is still so used to giving you instructions over legacy interfaces. They expect you to navigate to web pages, click buttons, they give out instructions for where to click and what to enter here or there. This suddenly feels rude - why are you telling me what to do? Please give me the thing I can copy paste to my agent.

In the coming months, you’ll want to make sure your API Product is usable by Agents. Here’s your checklist to plan your Q4 and 2026 Product Roadmap. Get a hi-res printable version and learn more about my upcoming course, Build AI-Ready APIs on @MavenHQ: maven.com/p/287814

For this first cohort I'll be including a full year of Lenny's Newsletter, which also includes access to an incredible Slack community and the full AI product pass - IYKYK

The official MCP Registry is here! An open catalog and API designed to solve how MCP servers are discovered. It doesn't host the actual server code. It stores metadata (server.json) that points to packages in other registries like NPM, PyPI, and Docker Hub, standardizing server distribution. - Stores metadata (server.json) that points to packages in other registries - Includes servers from NPM, PyPI, Docker, NuGet, and MCPB formats. - Encourages "sub-registries" on top of it, for curation, security scans, or custom metadata. - Dedicated Publisher CLI tool to easily add and integrate servers - REST API (GET /v0/servers) to programmatically discover and list servers - Community-maintained and includes a process for flagging and denylisting servers - Authentication with GitHub OAuth or custom domain DNS verification.

This weekend, I’m running a hands-on workshop for PMs, Architects & Engineers that want to upgrade their API skills. 🧑‍💻 You'll build an MVP with @OpenApiSpec and @Replit, and you'll publish your first MCP server! Build AI-Ready APIs is live on @Maven: tinyurl.com/aiapis

Anyone I know messed around with OGC APIs? Would love to geek out on details (ogcapi.ogc.org)

Hi @flysfo my airline has delayed my bag. It’s been a week and tracing shows it arrived at SFO on Monday. I’m waiting for it to be delivered but it’s taking too long. Is there a way to come pick it up? They are not giving me any helpful info about progress and I need my bag.

Hey @lufthansa you lost my bag on Saturday. I’m tracking it to a flight to that landed at the SFO airport on Monday. It’s Wednesday and it still hasn’t shown up. How long are you taking to deliver luggage in the SF area?
