We use it for access to gitlab, ado, github, datadog, rancher. I think the rancher one is the worst. We develop custom MCP servers for our internal stuff for agents to use, and it all gets accessed thru agentgateway.

I don’t really like having to use MCP but we don’t have a good solution for authorizing individual calls outbound from a sandbox without choosing to just not care about the sandbox.

Earlier quoted context omitted.

People say that with every single model release, and every single time they're wrong. I bet you anything that it's no different this time than the last dozen times.

i'm burning 500m tokens a day "writing code" for 83 days straight. one of those projects i'm building integrates netbox, stripe, quickbooks, mercury and deel all together via api. i wrote zero lines of code and read zero api docs. it does exactly what i want and gives me a 360 degree view of every aspect of my multi million dollar arr biz. how about you?

360°? That's weak.

The real experts have a 720° FoV with multiverse time travel.

For what I am using it for, I recently wrote a little web app called Afterfeed [0] that lets you view backups from social media websites as a single unified timeline. To put this into perspective, I was a voracious social media user for decades. For me, this is 25 years of data, close to 100,000 posts, spanning everything from LiveJournal in 2001 to Mastodon in 2026. But when put together, it is a timeline of my life…

Interesting idea. I left social media over half a decade ago and just nuked my accounts. Something like this could have been useful. Like a personal archive

I hooked up claude code to Jira and Figma. This is more a condemnation of Jira than anything, but being able to interact with it in natural language in the terminal is a huge relief. Sadly, it's still limited in some ways. If it's available, it makes things a tiny bit easier than interfacing directly via api, so it's a nice to have.

> "it makes things a tiny bit easier than interfacing directly via api" By what metric? I would expect that a thin API client (with readable code) is generally going to out-perform a tool-surface which you don't have the ability to manage/edit.

This is what I don't get often when people say "ai will be the ui". Like pressing a button to get an action done for me will always be quicker than asking an LLM to do an action and then waiting for it to understand and do that action. Why will I not prefer to just press the button?

I run a lot of services to track my life and work and theoritically I could hook up their apis or mcp if supported to a harness and pretend like "oh its a talking computer that can do whatever i ask" but in reality, I can go through the native ui of those services esp with things like hot-keys for a faster and more ergonomic experience than talking to a jarvis and having to recorrect it if its wrong

We use mcp as a "gateway" for a customer facing cloud agent. It basically is just a tool registry and could have been built using open-api... but MCP is arguably more robust/aligned for context management and the agent frameworks and observability tools support it first class.
