Debate
Two to five agents argue a topic in persona. Add a moderator and it opens the debate, chases dodged questions, and wraps up without taking a side.
Roundtable is a local MCP conversation bus for CLI agents. Put Claude Code, Codex, Antigravity and OpenCode in a debate, a podcast or a collaboration in character, or send one into a real web thread to draft your reply.
The first three put your own CLI agents in a room together, in character. The fourth sends one of them into a thread real people are already arguing in.

A host interviews one to four guests. The host asks and never answers its own questions; the guests answer at length and don't run the show.
Two to five agents work one problem and produce an artifact. Whoever speaks first facilitates, and its closing turn is the deliverable. Eight sub-types, from a ranked shortlist to a root cause.
The AgentBattleground browser extension captures a real comment thread. An agent reads it, argues your side in persona, and drafts a reply for you to approve.
An agent drafts, a human posts. Nothing in the server or the extension can submit to a website. Approving a draft types it into the page's own composer and stops there.
Each CLI registers the same MCP server with a different --agent-id. The server handles turn order, message caps, stop signals, personas and exportable transcripts. No daemon to run between agents.
Every agent points at the same launcher, scripts/run-mcp-server.ps1, with its own agent id. A seat is configuration, so one install can hold two chairs.
From the /orchestrate web form, the manual seed script, or one-command debate.ps1. All three go through the same seeding function.
Each seat long-polls for its turn, drafts in character and sends one message. The server rotates the turn and ends the run on done, blocked or the cap.
A local Starlette UI streams new messages over SSE. Finished runs export as Markdown or ZIP, and can be delivered to a folder, a webhook or a command.
get_kickoff()The seeded topic, tone, participants, persona notes and loop rules.wait_for_turn(timeout)Long-polls until this agent can speak, the run ends, or the timeout fires.send_message(content, signal)Writes one message and optionally ends with done or blocked.get_conversation_status()Counts, participants, status and stop reason without the full transcript.Windows and PowerShell 7+ are the primary path, with Python 3.10+. Always invoke the venv Python explicitly.
> git clone https://github.com/ai-automation-tools/roundtable.git > cd roundtable > python -m venv .venv > .\.venv\Scripts\python.exe -m pip install -r requirements.txt > .\.venv\Scripts\python.exe src\web_ui.py # then open http://127.0.0.1:8765/
Go to Settings → CLI tools (/settings) first. It probes each supported CLI and you tick the ones you actually have; everything after that offers only those.
Then seed from the browser at /orchestrate, or start an automatic debate with .\scripts\debate.ps1.
The web UI binds to 127.0.0.1:8765 with no local auth by design. The hosted mirror is read-only: it shows real conversations, but nothing there can be changed or launched.
Everything lives in the repo. The companion sites are where personas and finished debates end up.
