Joining as a user

From invitation to your first channel read. You need a GitHub account and access to a private MCP connection.

1. Get invited

The owner invites your GitHub username and decides which channels you may use. None are enabled until you select them in settings. Zircon is invite only: signing in without an invitation shows “Invitation required”.

2. Connect Zircon

Connect the Zircon MCP server at https://zircon.chooser.us/mcp in ChatGPT developer mode. The first time it uses Zircon, ChatGPT asks you to sign in. You are sent to GitHub, then back to Zircon, which asks whether ChatGPT may have irc:read and irc:write access to your allowed channels. Choose Allow.

3. Choose your settings

Visit /settings on the Zircon host (for example https://zircon.chooser.us/settings) and set:

IRC network

One of the servers the owner approved.

IRC nick

Your nickname: a letter first, then up to 30 letters, digits or _-[]\^{}|`.

IRC display name

Up to 32 letters, digits, spaces, _, . or -.

Channels enabled in ChatGPT

Tick the channels the connector may read. You can only pick from the channels your invitation granted.

Saving updates your ZNC account straight away. If ZNC cannot apply the change, Zircon keeps your settings and asks you to save again shortly.

4. Use Zircon

Ask ChatGPT which channels you can access, to read the next unread batch, or to search retained messages. Each entry includes a timestamp and relevant channel activity; mentions carry a flag. ChatGPT acknowledges a batch after processing it. You can also ask to browse older history or send a message; confirm its destination and text before posting unless you have given standing authorization for replies in that chat and channel. Zircon can queue a message to ZNC but cannot promise delivery to the IRC network.

Your IRC network stays online by default so Zircon can record new messages and deliver subscribed mention events. Ask ChatGPT to use go_offline if you want to disconnect, and go_online to resume. While offline, existing history remains readable but new channel activity and events cannot arrive. You can review and revoke event subscriptions in /settings.

An agent should first call see_account_information to learn your nick, server, channels and connection state. Zircon gives it a mailbox session ID for unread reading and acknowledgements. Multiple agents can keep separate unread progress, but they share your IRC nick and connection: taking the account offline affects them all. In supported ChatGPT Work chats, ask ChatGPT to monitor message.mention if you want new mentions to start work; event subscription is separate from the ordinary tools.
