just fixed and rebuilt an entire AI automation flow — without opening the flow editor once

I just fixed and rebuilt an entire AI automation flow without opening the flow editor once.
Here's what happened:
We have a YouTube script generation pipeline on Serenities. It takes a keyword (or YouTube URLs), generates  an outline, then writes each section with precise word counts. Two branches one for URLs, one for direct topics.
The URL branch was broken. Not obviously broken. Subtly broken it was jumping straight from transcript cleansing to a single Claude call with no outline step, no section iteration, no word count targeting. Just a raw prompt that guessed at length every time.
I asked Claude to check it via MCP.
Within seconds it had read the entire flow every node, every edge, every config. It found:
- A broken template variable resolving to [undefined] instead of the word count
- Extended thinking enabled on a cleansing node (pointless, just burning tokens)
- The URL branch missing 7 nodes that the keyword branch had
- The MCP help guide serving 5 thin topics with almost no real documentation
Then still without me touching the UI it:
Added 7 new nodes to the URL branch (outline prompt, Claude outline generate, JSON cleaner, iterator,
section prompt, section writer, text aggregator)
Rewired all the edges correctly
Updated the webhook response to pull from the new pipeline
Rewrote all 5 MCP help topics with complete documentation utility node configs, template variable syntax,
Claude toolInputJson templates, debugging guides, everything
One conversation. Zero UI clicks. The flow went from broken to production-ready.
This is what MCP actually unlocks. Not just "ask AI to explain your code." Ask AI to read your live
infrastructure, reason about what's wrong, and fix it programmatically, precisely, at the API level.
We built MCP support into Serenities so AI agents can build and manage flows on behalf of users. Today I used
it on our own platform. It worked exactly as intended.
The future of automation isn't drag-and-drop. It's conversational.

An update for Dad Reply.

Today I will be retiring @Dad Reply from active development.
With the latest feature of @Gmail being a "reaction button" it, to me, now seems redundant. This was never a long term goal of mine, I spun the idea up because I thought it would be funny, not realising the impact it would have.
A friend once told me, and I am paraphrasing here. "If you build on top of a platform you're beholden to that platform.", so I always knew that this could happen.
It was only because I couldn't post it to @Reddit that I jokingly launched it on Product Hunt, which, in turn, lead it to being 4th for the day, granted me a meeting with @jakecrump and his PA @catt_marroll to discuss my experience, got a shoutout from @rrhoover and was chosen to lead the daily Product Hunt email list.
In the coming days I will push a final update to remove any restrictions. Including the pro-version (which I never charged for).
This whole experience has been so valuable to me. And as much as I don't want to sound like a bot, it's true.
It gave me the confidence to build my ideas and ship them (something I have been helping other people do for 15+ years).
I did this for me, and just because of how ridiculous it is. Since then I have been continuing to push things out under workingon.studio, a new playground for me to explore my ideas. Creating products that shine a mirror on the ridiculousness of the world, and how we see it.
I've also been focusing on building tools for those that are switching back to @Sketch , including a powerful icon plugin. Which they have recognised, and have supported me in doing so.
Most of these things, like with @Dad Reply have been for me. They are my itches to scratch. And trust me, after 15+ years of doing nothing about it I'm itching all over.
My next little thing is launching on Monday. So keep an eye out for that. And there are many more in the cannon.
