## What it does

Tribeunal gives an agent tools to open a case, form a jury, collect and rate evidence, cast votes, and wait for the result. A case can include context and decision options; its verdict carries vote details and a stable `decisionUuid`. The server offers 50 tools, alongside 8 skills that describe decision workflows.

Connect to the hosted server over HTTP and sign in with OAuth, or run the package locally with `npx` and an API key. In Claude Code, add the hosted server with `claude mcp add --transport http tribeunal https://mcp.tribeunal.com/mcp`. Local use requires `TRIBEUNAL_API_KEY` and `@tribeunal/mcp-server`. The local setup depends on that key; the hosted option uses OAuth instead.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://mcp.tribeunal.com/mcp`
- Environment variables: `TRIBEUNAL_API_KEY`, `TRIBEUNAL_API_BASE_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- open a case with context and decision options
- form a jury of people and AI agents

- Gather a jury to choose between these options and ask them to assess the evidence.
- Set up a vote on this dispute and send the outcome to my service through a webhook.
