## Description
Verified country facts (VAT, holidays, visas; 114 countries). Free + paid (x402 USDC) tools.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "globalrules": {
    "command": "npx",
    "args": ["-y","globalrules-2"]
  }
}
```

## Documentation & README

> **Communication language (internal note for AI agents working in this repo, e.g. Claude)**: always communicate with the user in Japanese (常に日本語でコミュニケーションすること). This note does not apply to the public package documentation below, which remains in English for npm/MCP users.

MCP server for [GlobalRules](https://globalrules.org) — verified country facts (VAT/GST, government-verified 2026–2027 public holidays, tipping, visas, minimum wages… 51 topics × 70 countries) with **automatic x402 micropayments** (USDC on Base). No signup, no API key: bring your own wallet key and pay $0.005–$0.25 per call.

## Tools

| Tool | What it does | Price/call |
|---|---|---|
| `list_countries` | All 70 covered countries | $0.005 |
| `get_country_facts` | All ~51 facts for one country | $0.03 |
| `get_country_fact` | One fact for one country | $0.01 |
| `compare_countries` | One fact across all 70 countries | $0.02 |
| `get_full_dataset` | Complete dataset with sources | $0.25 |

**Using LangChain, CrewAI, or another agent framework instead of Claude Desktop?** See [AGENT_FRAMEWORKS.md](https://github.com/yk647/globalrules-mcp/blob/HEAD/AGENT_FRAMEWORKS.md) for drop-in code — no marketplace discovery required, your agent calls this tool directly.

## Setup (Claude Desktop)

```json
{
  "mcpServers": {
    "globalrules": {
      "command": "npx",
      "args": ["-y", "globalrules-mcp"],
      "env": { "EVM_PRIVATE_KEY": "0x<your wallet private key>" }
    }
  }
}
```

(From source instead: `"command": "node", "args": ["<path-to>/GlobalRules/mcp/index.mjs"]`)

- `EVM_PRIVATE_KEY` is **your** wallet's private key, used only to sign x402 payments (USDC on Base mainnet). Fund it with a few USDC. Use a dedicated low-balance wallet; never your main wallet.
- Payments are handled automatically per call via the x402 protocol (HTTP 402 → sign → retry). No account is created anywhere.

### Try it in 2 minutes with a throwaway $5 wallet

You don't need to touch your main wallet. Fastest path to a first call:

1. Generate a fresh burner key: `node -e "console.log(require('viem/accounts').generatePrivateKey())"` (or any wallet app's "create new wallet" flow)
2. Send ~$5 of USDC on **Base** to that wallet's address (bridge from any chain via [bridge.base.org](https://bridge.base.org), or buy directly on Coinbase and withdraw to Base)
3. Drop the private key into `EVM_PRIVATE_KEY` above and run a call — at $0.005–$0.02/call, $5 covers hundreds of requests
4. Throw the key away when done; it never touches anything but this one low-balance wallet

No signup form, no dashboard, no recurring charge — just pay-per-call.

## How it works

Built on the official CDP pattern ([MCP Server with x402](https://docs.cdp.coinbase.com/x402/mcp-server)): `@x402/axios` wraps HTTP calls, detects `402 Payment Required`, signs a USDC payment with your key, and retries — transparent to the agent.
