Building next-gen marketing agents at

[Ciobotaru Ionut @weeb0]

I've spent now - what? - 15 years around ads? a long time.. Longer than I expected.. esp. since I didn't target it specifically and I didn't realize it was an ecosystem at start.
My first adserver was open source and build in PHP in the early 2000s.

Those were the days...

[Ciobotaru Ionut @weeb0]

Probably the keynote I was most excited about? Couple of points:

1. Conversations using plugins grew ~10x this year - is this the new "appstore interaction model"?

2. Don't use tool search or hide tools behind list_command + run_command. expose every tool.
ChatGPT handles discovery, and admins get per-tool permissions

3. Keep schemas lean. ~3 in 4 tools are under 1kB. the biggest hit ~260kB, and when a schema is too big the model only sees "args: object" and loses the param guidance

4. Annotations are required for plugins. verified read-only tools get screened less and run faster - we've definitely been battling with this one :)

5. Only ~56% of servers use server instructions. keep them to ~500-1,000 chars, most important lines first

Last but not least (in the post prezi interview) -> @sarfata described some usecases for MCP events -> one of which being collaborating with agents on the same "canvas".
Such an unlock!

Looking forward to the demos later!

For those who missed it I took some pictures (cropped them with Codex); sharing them below 👇

@sarfata from @OpenAI shared a key takeaway during his “MCP in the Wild” keynote at AGNTCon + MCPCon NA: Make every tool discoverable and ensure annotations accurately describe its capabilities.

Because an agent can't reliably select the right tool if it doesn't know what that tool can do. Livestream: https://t.co/unqHE4HNIl

wait a second...

So if I’m getting this right: ChatGPT (via our @hypdai MCP plugin) could take actions inside our web app, provided our app supports WebMCP?

Is it just plug&play? (eg we could test today/tomorrow with latest ChatGPT desktop?)

We're working on our sidebar App so quite timely!

very cool update!!

[Ciobotaru Ionut @weeb0]

@mxstbr @grabbou do you mean that tool descriptions (potentially schemas) and so on can be updated without review?

I assume new tools would still need review right?

[Ciobotaru Ionut @weeb0]

@ericfranchi @aperiamventures Great to see we have a category forming! (=validation)

At @hypdai we're focusing on SMBs (and mostly walled gardens)

We also think this will be the main way not only media gets bought but how marketing/GTM/distribution gets run in the not so distant future.

[Ciobotaru Ionut @weeb0]

@mxstbr timely re-share as we're redesigning our MCP tools (we're at 150+ right now).

What we're looking into is grouping some of the tools in "clusters" (we basically have CRUD but across 3-5 surfaces (nr will increase))) - any pointers or thoughts on this?

We've researched couple of popular MCPs including some (ex: Posthog) using the "tool search" you mentioned previously (we're not going to follow this route)

[Ciobotaru Ionut @weeb0]

@ericzakariasson @bot Submitted @hypdai - I am already using it as custom plugin - installation was a breeze but hoping this will help others discover it!

[Ciobotaru Ionut @weeb0]

A nice “counter” to this is @eric_seufert series https://t.co/1olRvLSn8x basically making the point that existing online retailers will move and keep their share of commerce. Meaning majority of transactions will stay within those walls.

Couple of things can be true at the same time though.

I do see the supply side as an uncaptured opportunity - and I have two further thoughts on it:
- incumbents will capture quite a bit of it (and these days they move almost as fast as startups)
- “neo” providers will address those vertically (transaction vs lead vs booking - like you said) and deeper than incumbents - while partnering (to your point) and leveraging distribution via the same incumbents

[Ciobotaru Ionut @weeb0]

@derrickcchoi yup! much improved and great to get precise/actionable feedback on tools/issues before submitting :)

[Ciobotaru Ionut @weeb0]

In the interim - a prerequisite of of getting there - is that Anthropic and OpenAI (and similar others) become “platforms” - meaning the value they create across their ecosystems and the broader economy (consumer and enterprise) is higher than the value they capture = own revenues (and ideally valuations also).

Given how things are accelerating it seems only a matter of time.

AI will make everything free, including itself. The last domino to fall will be free energy, which is humanity’s final frontier.

[Ciobotaru Ionut @weeb0]

@nbaschez Oh, we’re excited!

And already building on it.

It enables going from giving tasks to agents (which will still happen ofc) to getting tasks from agents (or triggering other agents on events).

Somewhat new step in the autonomy/agent interaction ladder.

Super cool!!

[Ciobotaru Ionut @weeb0]

@mxstbr you guys are really cooking!

This is by far the most exciting feature released.
And I was already excited about the previous ones.

Need to get back to cooking with this one :)

[Ciobotaru Ionut @weeb0]

@jrlevine @jeff_weinstein @Muse Congrats! Quite impressive in such a short time!

Still waiting for our slot for @hypdai - we’re at the top for the other platforms and already work with many SMBs in the US.
I’ll check out the new process!

[Ciobotaru Ionut @weeb0]

@taskaid_ai @mxstbr @elephant_lumps worked. thanks a lot!

[Ciobotaru Ionut @weeb0]

@taskaid_ai @mxstbr @elephant_lumps @taskaid_ai - did you manage to make it work on the desktop app also?

[Ciobotaru Ionut @weeb0]

@mxstbr @taskaid_ai @elephant_lumps On the web we tried in work mode (and it worked); and the same for the desktop… but it didn’t..

[Ciobotaru Ionut @weeb0]

@mxstbr Reporting for duty!

Managed to get going a quick implementation of the sidebar entrypoint + composer resources.

Still tinkering with it but we'll probably push it live over the next few days.

PS: replied in the other thread about MCP Events too. Mostly working!

[Ciobotaru Ionut @weeb0]

@taskaid_ai @elephant_lumps @mxstbr we also managed to get the whole flow working on ChatGPT web!

Still having issues in Codex on the Mac app: we couldn’t get ChatGPT to subscribe. Any pointers on getting that part working? (this is local for now)

@ntkris @stellakaval We submitted it as part of @hypdai MCP - waiting on next steps!
