Official MCP server

The @mupag/mcp-server@0.1.0 release exposes MuPag tools over stdio and is restricted to the sandbox. Its MCP Registry discovery identity is br.com.mupag/mcp-server.

:::info Available Version 0.1.0 is published on npm and in the official MCP Registry. :::

{
  "mcpServers": {
    "mupag": {
      "command": "npx",
      "args": ["-y", "@mupag/mcp-server@0.1.0"],
      "env": {
        "MUPAG_API_KEY": "sk_test_your_key_here",
        "MUPAG_ENV": "test"
      }
    }
  }
}

The server can create charges and checkout sessions, manage subscriptions, request refunds, and read reconciliation data. Every mutation requires an idempotency key, an approval reference, and explicit confirmation. It rejects production, PAN/CVV, mismatched credentials, and error output that might expose secrets or PII.

The immutable npm artifact is the release source. The same version is published in the official MCP Registry, on Smithery, and has been submitted to MCP.so through the public directory request. The 0.1.0 MCPB bundle for local servers is also available from the public distribution repository. No directory should point to latest.

Recommendations

• Give the agent the overview and quickstart first.
• Keep the agent on server-side examples whenever sk_* is involved.
• Use the changelog before regenerating clients, prompts or automations.
