Xzar MCP server

Crash-test your AI agent on real professional decisions. Xzar gives your agent real cases, cut at the moment of decision, and grades its answer against what the professional actually decided. Most cases were decided after current models were trained, so they can't have been memorized; fresh ones are added monthly.

Live today:

  • Tariff classification: real U.S. classification decisions, graded exactly at 2, 4, 6, 8 and 10 digits, with a consistency check (the same case asked twice). Testing a tariff classifier? See https://xzar.si/scorecard
  • Patent examination: first action, response and appeal.

More fields are on the way; ask for yours at https://xzar.si.

Setup

  1. Get an API key (with $5 of free credit) at https://xzar.si/signup.html
  2. Add the server to your MCP client:
{
  "mcpServers": {
    "xzar": {
      "command": "uvx",
      "args": ["xzar-mcp"],
      "env": { "XZAR_API_KEY": "your-key" }
    }
  }
}

Hosted connector (no install)

In Claude or any MCP client that supports remote servers: add https://api.xzar.si/mcp and sign in with your Xzar API key.

Claude plugin

The plugin/ folder is the Xzar plugin for Claude. It bundles the hosted connector with two skills: crash-test, which runs a task end to end and explains the score, and xzar-request, for custom tests, pilots, quotes and training access. In Claude Code:

/plugin install xzar --marketplace xzar-si/xzar-mcp

Tools

ToolWhat it does
start_taskStart a task: the case, the instructions and the tool budget
search_librarySearch the case's reference library
read_publicationRead one library item
search_rulesSearch the professional rulebook for the task
read_ruleRead one rulebook section
submit_answerSubmit the decision; returns the exact score and the grade receipt
request_serviceAsk for a custom test for your field, a pilot, a quote, or training access; get a reference and next steps
get_scorecardYour agent's scorecard across tasks
get_usageCredit balance and usage

Answer keys never leave Xzar's servers. This package holds no tasks; it calls the Xzar API with your key.

Pricing

Prepaid credits, charged per task. See https://xzar.si/docs.html. Pilots and ongoing testing: https://xzar.si.

الأسئلة الشائعة

Crash-test your AI agent on real professional decisions, graded against what actually happened.

كيف أثبّت Xzar؟

هل يحتاج Xzar إلى مفتاح API؟

نعم. يتطلب XZAR_API_KEY، وتضبطها في إعداداته.

هل Xzar مفتوح المصدر؟

نعم. شيفرته متاحة على GitHub بترخيص MIT.

من يصون Xzar؟

ينشره xzar-si. يدرجه AI.tn لكنه لا يصونه ولا يوصي به.
