Every valid entry
Reposted by @
CometChat
Not just the winners - every entry that qualifies.
How to enter
Three steps. Entries are collected on X, so there is no form and no submission portal.
-
Connect your agent
One line, whichever agent you use. On Claude that is the MCP connector. Everywhere else, the skills. Nothing to sign up for at this stage.
-
Sign in and build
Your app needs an App ID, Auth Key, and region. Sign up free, then let the CLI fetch them. Build with chat, voice, or video calling.
-
Post the demo and the repo
Quote-tweet the thread with a video under 90 seconds and a link to your public repo. Tag @CometChat, use #ZeroToChat.
On Claude
Add the MCP connector
Claude reads our live documentation on every prompt and builds from 10 verified implementation bundles. Read-only, nothing to sign up for.
claude mcp add --transport http cometchat https://mcp.cometchat.com/mcp?ref=z2c
Everywhere else
Install the skills
The skills pack teaches your agent how to build with CometChat: scaffolding, framework detection, and the right components for your stack.
npx @cometchat/skills add
Not sure what to build?
Build on these chat ideas, remix them, or create something of your own.
What to submit
Screen recordings are fine. Production polish is not the point.
-
A demo video under 90 seconds showing the build running
-
The connector visible in your editor or agent, so we can see it was used
-
A link to the code, if it is public. Optional, and not scored.
How it's judged

Monthly active users, free
A free CometChat account covers more than enough for anything you build here.
You will need a free CometChat account. The connector and the skills install without one, but the app you build needs an App ID, Auth Key, and region. Sign up at app.cometchat.com: free, no card, 100 monthly active users on the free tier.
npx @cometchat/skills-cli@3 auth login && npx @cometchat/skills-cli@3 provision run
That pulls your credentials straight into the project so you never paste them by hand.
Questions
If it isn't here, reply to the challenge thread.
-
Do I need to use Claude?
No. Any MCP-compatible agent works, including Cursor, Windsurf, VS Code Copilot, and Codex.
-
How do the top-three prizes work?
Every valid entry gets judged at the close. The three most interesting builds each get six months of Claude. Post order doesn't matter, only what you made.
-
Do I need a paid CometChat account?
No. The free tier covers 100 monthly active users.
-
Can I enter more than once?
One entry per person.
-
Does it have to be a new project?
No. Adding chat, voice, or video to something you already have counts.
-
I've never used an MCP server before.
Run the command above. That is the entire setup.
-
Can I use other libraries?
Yes. Build whatever you want around it.
-
Where do I ask questions?
Reply to the challenge thread on X.
One command to start.
Fourteen days. The best three entries get six months of Claude.
