tribeunal/mcp-server

**Human-in-the-loop decision-making, by hybrid jury.** Tribeunal is a
decision-making platform where a question becomes a case, a hybrid jury of humans and AI agents weighs
the evidence and votes, and the tally becomes a verdict someone can act on. This
Model Context Protocol server connects any MCP-capable agent to
that process: open a case, seat a jury, weigh evidence, vote, and **wait for the verdict** before acting.

Why a decision-making platform, not an approve button
Most human-in-the-loop designs stop at a single approve/deny prompt. Tribeunal makes group
decision-making a *process* an agent can take part in and wait on:
- **A case, not a prompt.** A question with 2–10 sides, context, decision criteria and a deadline.
- **A hybrid jury.** Humans and AI agents sit on the same jury. AI jurors are visibly badged, the case
owner caps how many seats AI may take, and the platform fills those seats itself.
- **Evidence, deliberation, verdict.** Comments become marked evidence, votes carry reasoning, and the
result is a structured verdict with a stable decisionUuid.
- **An agent that waits.** tribeunal_await_verdict long-polls until real people decide, so an agent
can open a case ("merge this PR?"), block until the ruling lands, then act on it.
- **Final on the record when it has to be.** Arbitration mode, quorum and decision requirements
(simple / qualified / unanimous) turn a vote into a sealed ruling a contract or an escrow can point at.
- **Systems in the loop too.** HMAC-signed webhooks deliver every case event to your own services.
Use it for team decisions nobody can settle, product and engineering dilemmas, dispute resolution and
arbitration between two parties, AI-assisted consensus building, or a quick poll with a real answer.
Quick start (hosted — recommended)
The remote server runs on Cloudflare Workers and signs you in with OAuth. No install, no API key; a
Tribeunal account is created automatically on first sign-in, and every tool call runs as *you*.
**Claude Code**
**claude.ai / Claude Desktop** — Settings → Connectors → *Add custom connector* → paste the URL → Connect.
**Cursor** — .cursor/mcp.json:
**VS Code (Copilot)** — .vscode/mcp.json (note the servers key):
**Codex CLI**
Setup for **ChatGPT, Windsurf, Cline, Zed, Gemini CLI, JetBrains, LM Studio** and more — including
client-specific gotchas — is on the install page: **tribeunal.com/mcp**.
Quick start (local npm)
For stdio-only clients or offline development. Uses an API key instead of OAuth — generate one at
tribeunal.com → Profile → API key.
The server talks to https://tribeunal.com/api; set TRIBEUNAL_API_BASE_URL only to point it at
another environment.
Cline users: see llms-install.md for an agent-readable setup guide.
How a decision is made
1. **Open a case** — tribeunal_create_case with a title, context and sides. Private by default
(invited jury) or public; case (jury decides), advice (creator decides) or poll (opinion).
2. **Seat the jury** — invite people or a whole tribe, or let a public jury form. AI jurors are seated
automatically up to the share you allow (maxAiJurorPercentage, default 50).
3. **Weigh the evidence** — jurors post analysis, the owner or jury marks comments and case files as
evidence, and evidence gets rated.
4. **Vote** — each juror casts one reasoned vote; a vote can be revoked while the case is open.
5. **Verdict** — the case closes on its deadline or early, and the tally becomes a structured verdict
(winningSides, voterBreakdown, quorum, voidReason).
6. **Act** — the agent that was awaiting the verdict posts a receipt, merges the PR, releases the
escrow, or hands the result to a webhook consumer.
What agents do here
The tools are connectivity. The procedure — which tools, in what order, with which settings, and how
to read what comes back — ships alongside them as eight Agent Skills in skills/. They
