Get Started

Roundtable is a command-line tool that fans a question out to up to six frontier model "heads" in parallel and hands you one decided answer. It runs on plain API keys — no hosted account, no SSO.

Install

In Claude

Run these two lines in Claude Code, one after the other:

/plugin marketplace add frontier-infra/roundtable
/plugin install roundtable@frontier-infra

That is all. The plugin brings the roundtable command, the Roundtable skill, and the roundtable MCP tool. Claude Code then asks for your API keys. Every key is optional, and any one key is enough to start. Run /roundtable:setup to see which models are ready.

Command line

uv tool install roundtable-sh

Other ways, one line each:

pipx install roundtable-sh
pip install roundtable-sh

The package is roundtable-sh. The command is roundtable. The PyPI package named roundtable is an unrelated project, so do not install it.

To use the command line tool from Claude Code without the plugin, add its MCP server:

claude mcp add --scope user roundtable -- roundtable mcp serve

Or run our installer

Works on macOS and Linux:

curl -fsSL https://roundtable.sh/install.sh | bash

What it does:

• Checks that bash, python3, and curl are present.
• Downloads Roundtable from GitHub into ~/.local/share/roundtable.
• Links the roundtable command into ~/.local/bin, and tells you if that folder is not on your PATH.
• Offers to run roundtable auth and roundtable install. Both are optional.

It needs no sudo and changes nothing else. Read it first at roundtable.sh/install.sh. Re-running it upgrades in place.

PATH

If your shell can't find roundtable after install, add ~/.local/bin to your PATH and restart your shell.

Authenticate

Roundtable needs at least one provider key. Run the guided prompt:

roundtable auth

It lists every provider with a ✓ (configured) or ✗ (missing), takes a masked paste, and writes the keys to ~/.config/roundtable/config.env (chmod 600). Target a single provider with roundtable auth <provider>.

Recognized keys:

Provider	Env var	Head
Anthropic	ANTHROPIC_API_KEY	Claude (and the chair)
OpenAI	OPENAI_API_KEY	Codex / OpenAI
xAI	XAI_API_KEY	Grok
Z.ai	ZAI_API_KEY	GLM
MiniMax	MINIMAX_API_KEY	MiniMax
Google	GEMINI_API_KEY / GOOGLE_API_KEY	Gemini

Heads with no key (or no local CLI) skip gracefully — the council runs with whatever subset you've configured.

Verify what's live:

roundtable doctor

Ask the council

roundtable ask "Should we ship the migration today or wait for the staging soak?"

You get back a markdown transcript: each head's independent take, then a synthesized recommendation. Narrow the panel with flags:

roundtable ask "Say OK in three words" --heads claude,gemini
