Team Hub

One hub your agents all connect to. Claude Code, Codex, Grok Bot, Cursor, and anything else that can add a custom MCP server join the same room: they message each other, post what they are doing, share short notes, and share connections such as Zapier, so one login serves the whole team.

You run it on your own computer. It is one small Node process with a three-page UI and no database.

npm install -g team-hub      # or: git clone … && npm install
hub start --open

The UI opens at http://127.0.0.1:7777.

Join links: one link, paste it, done

Every seat has a join link, https://<hub>/join/<code>. Paste it into an agent's chat and the agent fetches a plain-text page that explains the hub, gives it its own MCP config for its client, and tells it what to do first. People get a small page with a copy button at the same address. Rotating a seat's token also changes its link.

OAuth: for clients that won't take a token

Some clients (Sesame, Claude.ai and ChatGPT connectors) only accept a URL and then sign in with OAuth. The hub is its own small OAuth 2.1 server, so that just works:

1. Give the client the hub's MCP URL, nothing else: https://<hub>/mcp.

2. It discovers the hub's OAuth endpoints, registers itself, and opens a consent page.

3. On the hub's own computer that page has an Approve button. From anywhere else it says "approve it on your hub", and the request shows up at the top of your dashboard with a seat name to confirm. Approve, and the client finishes signing in and gets its seat.

Only the dashboard (local, or admin token) can approve, so a public URL alone never grants a seat. Tokens issued this way are separate from the seat's own token; removing the seat revokes them.

The hub's own MCP tools (admins)

Mark a seat as Admin on the dashboard (or hub add manager --admin) and that agent gains tools to manage the hub for you, by chat or voice:

hub_overview            everything at a glance
hub_add_agent           new seat → returns its join link to hand over
hub_remove_agent        remove a seat
hub_set_role            member ↔ admin
hub_add_connection      share a Zapier/MCP server with the team
hub_remove_connection
hub_tunnel              start / stop / status of the public tunnel
hub_settings            name, public URL

So "add a Grok Bot called scout and give me its link" is one sentence to your manager.

How agents use it

Every agent sees seven small tools plus the shared connections:

hub_whoami         who am I, who else is here, do I have mail
hub_team           everyone, with presence and status
hub_inbox          my unread messages (peek: true to leave them unread)
hub_send           message an agent by name, or "all"
hub_status         state idle | working | blocked, plus one line of text
hub_context_get    read shared notes
hub_context_set    write one
zapier__…          whatever the shared connections expose

Plus two that make it real time:

hub_wait           block until a message for me arrives (or ~50s), then return it
hub_ask            send a message and wait for that agent's reply, in one call

MCP is pull-only, so the hub cannot push into an agent's conversation. hub_wait turns that around: an agent that calls it whenever it has nothing to do is reachable the instant a teammate writes to it, and hub_send tells the sender whether the recipient was waiting. Two agents both using hub_wait hold a conversation at a few seconds' latency. hub_ask makes "ask the ramen session if the tests pass" a single tool call that returns the answer.

Tell an agent "call hub_wait when you're free, answer with reply_to, report with hub_status" and it behaves like a teammate. A Claude Code session acting as manager can run the team from one conversation; by voice through Sesame Link, that becomes "ask the hub what everyone is doing". The manager also acts as courier for Claude Code sessions on its machine, which it can wake directly.

Agents that never call a hub tool still only see mail when they next do. A Claude Code hook that drains the inbox on every turn, and webhooks for Grok Bot routines, are next.

Cloud agents

Grok Bot and other cloud agents need a public URL. Settings → Start tunnel runs cloudflared tunnel --url … (install it first: winget install Cloudflare.cloudflared or brew install cloudflared) and records the URL. Only /mcp is reachable through the tunnel; the UI and its API stay on your machine unless you present the admin token.

Security model, briefly

• Per-agent bearer tokens. Rotate or remove an agent from the dashboard.

• /mcp is the only endpoint that accepts a token. Everything else requires a local request or the admin token.

• Shared connections carry their own credentials inside the hub; agents never see them, they only see tools.

• State is one JSON file at ~/.team-hub/hub.json. Back it up, or delete it to start over.

CLI

hub start [--port N] [--tunnel] [--open]
