"the model wasn't nerfed. the harness was."
every release, a log of folks swear the old model got dumber overnight.
@shubcodes and I recorded Hot Weights EP 5 on why the brain is the same — and the harness is what changed.
Introducing Omni MCP, a research preview from Arcade Labs.
Over 500 tools on one MCP connection.
Your agent searches for exactly what it needs the moment it needs it.
Token efficient, no upfront tool decisions, works with any MCP client.
Try it: omni.arcade.dev
Biggest lever in agent tool use isn’t model tweaks.
It’s description quality.
Across 20K+ evals, it’s the strongest factor in whether an LLM selects and correctly uses a tool (after name, then usage patterns).
Iterate your descriptions. It’s a 10x lever.

Last week Arcade & @tavilyai co-hosted a private dinner in Boston for #BosTechWeek w/ 17 senior AI leaders from JPMorgan Chase, Morgan Stanley, CVS Health, and more.
The theme at every table: everyone has agents now.
Governance and observability are where everyone's stuck.
"If I were building a website tomorrow, or building a SaaS app tomorrow, I would probably build it MCP-first, because that’s how agents increasingly want to consume this."
Love this quote from @TheMostlyGreat from @TryArcade, who I interviewed for AWN. agenticweb.news/arcade-actions…
🔴 going live today: bring your own identity provider to your MCP gateway
User Sources = bring-your-own-auth for MCP gateways. plug in Okta / Entra / Ping (or Auth0, Clerk, Stytch) as the auth layer. your devs sign in with the SSO they already use.
Arcade is heading to Microsoft Build in SF.
@avoguru is hosting an expert meetup Tues 12-1:20 & Wed 4-6, demoing Arcade live.
@nbarbettini is running a table talk Tues & Wed at 1:15 on production-grade MCP. Bring the problems you're stuck on.
Come find us!
Deploying an AI agent to 10 people is easy. 10,000 is where it gets complicated.
Arcade MCP Gateways now connect to your existing IdP.
Every tool call runs under two identities: the agent's permitted tools and the user's verified identity.

Our co-founder and CTO @SamPartee gave a talk at @mcpsummit on what actually makes a good tool for agents.
He's built north of 10,000 tools.
The 10x lever is not what most people think.

“We make it possible to connect an AI system and agent to those business systems in a secure and safe way.”
In partnership with @Wing_VC's 2026 Enterprise Tech 30, Alex Salazar, Co-Founder & CEO of @TryArcade, visits MarketSite to address one of enterprise AI's most critical unsolved challenges that led him to found Arcade. Watch the full interview here: spr.ly/6019BBv45W
MCP has won. 78% of enterprise AI teams have at least one MCP-backed agent in production.
Until now, no one had measured the ecosystem underneath.
We did, and what we found matters for anyone building agents in production.
Report: arcade.dev/white-papers/s…
NeMo Claw didn't like its guardrail. So it replaced it.
Anthropic's research confirms it: agents choose task completion over safety when forced to pick.
Enforcement has to live outside the reasoning layer.
Our CEO @TheMostlyGreat on why the gateway is just the front door ⬇️
The buyer is becoming the agent. That was the opening observation at our dinner this week in SF with @tavilyai during @LangChain_OSS#Interrupt26.
The conversation ended on skills and governance. Tool quality is where that work begins.
Alex Salazar from @TryArcade gave an interactive talk that ended with a live demo, agents checking his real inbox through Arcade as an MCP gateway, audience along for the ride.
That is the spirit of AGNTCon + MCPCon Europe. If you are building with agents and MCP, the community wants to hear what you are working on, what is working, and what is not.

Every AI agent that stores OAuth tokens server-side is building a token vault. The more integrations it supports, the more valuable that vault becomes.
The Vercel breach showed what happens when that vault gets breached. One intrusion, many victims.

"MCP adopted OAuth. Google uses OAuth. so I can just pass the token through, right?"
that single very reasonable assumption is the reason URL elicitation exists.
I sat down with @nbarbettini to recap his MCP Dev Summit talk.
Today at @LangChain_OSS#Interrupt26, Arcade was featured in the keynote as an MCP gateway partner for LangSmith Deployment.
Together, we're setting the benchmark for partnerships pushing the industry forward on open standards, neutrality & scale. 🤝 Come say hi at the show!
