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.

[Jared Friedman @snowmaker]

"Make something agents want"

[Emmanuel Paraskakis @manp]

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.

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. 🚀

@Benioff APIs, MCP, CLI & Skills are the atomic, irreducible expression of product value - and it's what agents want.

[Hanh Nguyen @fashiongiik]

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

[Ben Tossell @bentossell]

agents are the software market from now on

build something agents choose

cli/api first

[Aaron Levie @levie]

@karpathy 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.

[Aaron Levie @levie]

[Emmanuel Paraskakis @manp]

@levie APIs as the atomic irreducible core of your product that AI or competition can't take away. Perfect for agents.

[Andrej Karpathy @karpathy]

💯 "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.

[Emmanuel Paraskakis @manp]

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

[Emmanuel Paraskakis @manp]

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!

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.
