launching today! it's an open source catalog of every products MCP / API / CLI / GraphQL server and how to authenticate to them deep links to generate api keys, 1 click copy spec urls, it's still early but i've been loving having it

made a PR to portless to enable multiple apps to all work on localhost:3000 at the same time feels magical, solves the issue i have with auth all being on different redirect urls

These problems are very solvable at this point, for instance Executor requires approval of non GET actions `npm i -g executor` to use it, you shouldn't have to be afraid of what your agent is going to do

did more prototyping on this one, calling it `meshnet` what you see here is each chat on its own VM, but you're just developing on localhost:3000 so it feels local def something here, open sourcing the prototype and prompt so hopefully someone does something cool with it

Interesting trick from the latest Mr. Beast video - He uses a progress bar that starts moving quickly, then slows to a crawl in order to make viewers less likely to skip the sponsor segment as they think it will be over quickly

I genuinely believe GitHub desktop is the best Git client for most people The design is simple but it's excellent for day to day work of swapping branches, cherry picking, undoing commits, stashing, previewing PRs - one of their best products

MCP sucking is a harness problem, not an MCP problem MCP unlocks behavior that is fundamentally impossible to get via CLI or APIs Bad auth, too much context usage, all get solved with an execution layer - your agent writes code to progressively discover and call tools

I'm now building Executor full time as a startup! The state of tool calling is a mess: - Everyone is using different agents - You have no idea what actions are going to run - Destructive actions are treated the same as normal Executor lets you set up everything once & use it with any agent. You're able to control what tools can be called, require approval on destructive actions, and invite your team to all use them. Under the hood, it's built on codemode to let you add thousands of tools with 0 context bloat. I've been using it for a month so far and it has completely changed how I interact with agents. There's so much to be built here, immediately next up on the roadmap is workspaces, skills, workflows, and generative ui. Everything is being built open source over at there's a lot more coming on an SDK to embed it into your own agents, a self hostable cloud app, and plugins There's an early beta version over at It's very early on - if you hit any bugs let me know and I'll get them fixed up, excited to share more as I build it!

Doing Executor's YC launch today! Executor is your tool gateway - it gives you one place to sign in to all of the services you use and then every agent adopt (Hermes, Codex, OpenClaw, etc) carry over the same signed in accounts, permissions, etc Executor gets a ton right about how tool calling should work. It supports multiple accounts for all integrations including things like Gmail, it lets you filter which tools are available for agents. We see teams adopt Executor and immediately setup their whole company with it because its the first time they've had the ability to integrate with everything they use - give it a try!

I'm concerned we're entering a local maxima with CLIs, they're the wrong interface for agents The right interface is regular REST APIs with CIMD (same spec that MCP uses to allow for dynamic client registration) Your agent then writes code to interact with the API (like Cloudflare codemode) Think about how this works for humans today for the following action: "I want to set a DNS record on my domain" -> You Google "Vercel set DNS records" -> Docs page tells you what buttons to press -> You press buttons on a website, those call an API Now for agents, they search Google: -> "Set DNS record on Vercel Domain" -> they land on the same docs page, except it outlines what api endpoints are used as well -> the agent then calls those api endpoints for you, credentials are dynamically inserted where the agent can run them -> (optional) set auto approval policies / require approval of all non GET options by default You don't need separate interfaces for agents, nor do you really need separate skills for them CLIs have terrible discoverability, no input / output typing, they're harder to make profiles for for allowed / disallowed tools They work as a stop gap solution, but companies should be focusing on making good docs and APIs, not CLIs I've been prototyping this over at (open source if you want to play with what this world would look like - still early on it so appreciate feedback - open source and can run completely on your machine

this is one of the most common problems on react sites, but it's solvable with less than 10 lines of javascript you can see how what i type gets wiped out after hydration, but if you use an inline script tag like shown in this demo your input seamlessly transitions

i hate the way tool calling works today, so i built a fix for it its called `executor` and it lets your agent run code to call any API / MCP / GraphQL server rather than installing CLIs this is a soft launch, you can try it with npm i -g executor but im still making it great
