Hello everyone, I'd like to give you all a quick update on the PerfAgent progress! It's been a wild ride since the inception of PerfLab, from forking DevTools to build a new experience using all of its power and trying to take my owns spin on Performance Tooling for all devs!

I'm also open for consuntancy, so reach out if you are looking to collaborate.

I've been building v0.perflab.io agent.perflab.io and other cool stuff, with V0 SDK, AISDK and Mastra

Also have interest on browsers and DevTools with my own projects and forks of it to ship my own autonomous agents.
V0 MCP Server
Model Context Protocol (MCP) server that exposes v0.dev APIs through the Streamable HTTP pattern. Built with Hono framework and deployed on Vercel.

Am currently trying to get my own thing off the ground prototyping an intersection of browsers and personal assistants and also autonomous coding agents that are capable of self improving.

Hit me up know if you know of any oportunities around 🫡

Hello everyone, I have just heard that the company I'm a lead engineer for is going to downsize so I'm going to look for the next thing from next week.

I'm looking to work with AI engineering and am shipping lots of different code automations and agent workflows.

Whist trying out my demo for the Agentic Perf Analysis and Debugging, I managed to use my V0 and my DevTools MCP servers to debug one of my V0 demo chats.

Using animation frame insights no less 😃

We're almost there!

After spending the week hacking OAuth support into Mastra MCP client class and getting the toolcall aproval workflow to an MVP state this sprint is soon coming to an end.

I've seen and am following the great work being done by the
@chromium.social team on new primitives for browsers, and am experimenting with my own forks of DevTools and Chromium.

I'm exciteed for what's to come, and believe that the platform will thrive!
webx.bsky.social
There's a larger goal of mine here, my experiments with MCP is to try to better understand how to enable good primitives for AI native systems.

Updates on PerfAgent, after spending some time implementing v0.perflab.io MCP server it's now time to create PerfAgent's MCP client.

It will be a great way to expose the agent to external services and agents such as @sentry.io Seer, and my own servers too, like V0.

PerfAgent will be a web MCP client fully spec compliant. Great playground for this.

After getting the spec compliance, I'll move to MCP UI and then we'll start having fun.
webx.bsky.social
I've managed to implement OAuth into Mastra MCP client (on a fork of mine) and now it talks to my V0 remote MCP server (that uses OAuth).

Gotta work on the HITL parts of the MCP tool call as the spec requests, but we're moving now 😎.
webx.bsky.social
I've started to implement the client using Mastra MCP client, since I already use Mastra as my agent framework with AI SDK.

But Mastra supports only setting the auth header, and do not (at this time) support the full OAuth flow.

Good thing is, I've been playing lots with OAuth flow for MCP servers
