Use Roundtable from your AI

Roundtable is an MCP server. Any AI app that speaks MCP can call it: Claude, ChatGPT, Codex, Cursor, VS Code and more. Ask your AI to "ask the roundtable", and it convenes the table and brings back the verdict.

• The verdict comes first: the pick, how sure the table is, what would change it, and three next steps.
• The full transcript comes with it as a resource (roundtable://run/<id>).
• A run takes one to several minutes, or about 14 minutes in Deep Think. Roundtable sends progress to your AI while it works, so the AI keeps waiting.

In the Roundtable app

Open Settings, then Use Roundtable from your AI.

App	How
Claude app	Press Connect to the Claude app, then quit and reopen Claude.
Claude Code	Press Connect to Claude Code, then start a new session.
Codex CLI	Press Connect to Codex, then start a new Codex session.
Cursor	Press Connect to Cursor. In Cursor, open Settings, then MCP, and turn roundtable on.
Any other MCP app	Open Another AI app? Copy its setup and paste the setup into the app.
ChatGPT	Switch on Share with ChatGPT (below).

Nothing changes until you press a button. Each button writes only that app's settings file, and they keep a dated backup of it.

ChatGPT

ChatGPT runs in the cloud, so it cannot reach an app on your computer directly. The Share with ChatGPT switch gives Roundtable a private web link through a Cloudflare quick tunnel.

1. Install cloudflared once. Mac: brew install cloudflared. Windows: winget install --id Cloudflare.cloudflared.
2. In Roundtable, switch on Share with ChatGPT and press Copy link.
3. In ChatGPT on the web (Plus, Pro, Business, Enterprise or Education): open Settings, then Security and login, and turn on Developer mode.
4. Open Plugins, press +, paste the link as the MCP server URL and choose No authentication.
5. In a chat, choose Developer mode from the + menu, pick Roundtable, and ask: "Use the Roundtable app's roundtable tool to ask: ..."

The link holds a secret token, so share it with no one. Switch it off and the link stops working. The next time you switch it on, you get a new link and a new token. Every call shows in the app, with the question and the result.

OpenAI API (Responses API and Agents SDK)

Switch on Share with ChatGPT, then open For the OpenAI or Claude API for the server URL and the token. Add a remote MCP tool:

{
  "type": "mcp",
  "server_label": "roundtable",
  "server_url": "https://<your-link>.trycloudflare.com/mcp",
  "authorization": "<token>",
  "require_approval": "never"
}

Claude API and Claude connectors

• Claude API (MCP connector): add {"type": "url", "url": "https://<your-link>.trycloudflare.com/mcp", "name": "roundtable", "authorization_token": "<token>"} to mcp_servers.
• Custom connector on claude.ai: add a custom connector with the full link (.../mcp/<token>) and no OAuth. On your own computer, the Claude app connection above is simpler.

From the command line

roundtable mcp serve                          # stdio, for apps on this computer
roundtable mcp config --client codex          # setup for claude, claude-code, codex, cursor, vscode, windsurf, generic
roundtable mcp serve --http                   # Streamable HTTP at http://127.0.0.1:8765/mcp, prints a new token
ROUNDTABLE_MCP_TOKEN=$(roundtable mcp token) roundtable mcp serve --http --port 8765
cloudflared tunnel --url http://127.0.0.1:8765   # a public https link for remote apps

Codex stops a tool after 60 seconds unless told otherwise. The setup Roundtable writes sets tool_timeout_sec = 1800.

What a remote caller can do

• Only the roundtable tool. No shell, and no files on your computer.
• Every request needs the token, as Authorization: Bearer <token> or at the end of the link.
• The server listens on this computer only (127.0.0.1). Only the tunnel makes it public.
• It can attach public web links, never a private or local address, and send documents as text.
• Limits: 6 roundtables a minute and 2 at once. Change them with --calls-per-minute and --max-running.
• Each AI seat still answers in its own private space. It cannot see your files or run commands.
• The roundtables use the AIs and plans on your computer.
