Overview

Description from the maker (original English)

Secure agent purchasing with human-approved virtual cards, receipts, and audit trails.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Other
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http allowance https://mcp.useallowance.com --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "allowance": {
      "url": "https://mcp.useallowance.com",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "allowance": {
      "type": "http",
      "url": "https://mcp.useallowance.com",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }

Common questions

Is Allowance MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Allowance MCP

Allowance is a payment security layer for AI agents. It lets humans approve scoped purchases on their phone while agents complete checkout with limited-use payment credentials instead of the human's real card.

Allowance MCP exposes that flow to MCP clients: agents can request approval for a specific purchase, receive a scoped virtual card after approval, complete checkout, and report receipts and final charged amounts back into an audit trail.

This repository is the public listing and configuration home for the hosted Allowance MCP server. The implementation repository is private.

Hosted Server

  • Server URL: https://mcp.useallowance.com
  • Transport: streamable-http
  • Official registry name: com.useallowance/allowance-mcp
  • Official registry URL: https://registry.modelcontextprotocol.io/v0.1/servers/com.useallowance%2Fallowance-mcp/versions/latest
  • Company site: https://useallowance.com
  • Discovery metadata: https://useallowance.com/.well-known/mcp.json
  • Product docs: https://useallowance.com/mcp

Authentication

Allowance MCP uses OAuth. Connect your MCP client to https://mcp.useallowance.com and complete the Allowance OAuth flow when prompted.

After OAuth completes, MCP clients send the issued bearer token on tool calls. Users should not create or paste standalone API keys for normal MCP use. Do not commit tokens, card credentials, or checkout PII.

Core Flow

  1. The agent creates an allowance request for a specific purchase.
  2. The human approves, denies, or lets the request expire on their phone.
  3. If approved, the agent completes checkout with scoped payment credentials or waits for Allowance remote fulfillment.
  4. The agent reports success or failure, including receipt and charged amount details when available.

Human phone approval is the spending authorization. After approval, agents should not ask for another final confirmation unless the realized total exceeds the approved cap, checkout requires unavailable information, or the item materially differs from the approved request.

What Allowance Controls

  • Spend scope: merchant, amount cap, purchase reason, and expiration.
  • Payment exposure: agents get limited payment credentials instead of the human's real card.
  • Checkout data: approved contact, shipping, and billing fields are available only when needed for checkout.
  • Auditability: requests, approvals, card issuance, purchase attempts, receipts, and failures are recorded.
  • Revocation: humans can pause or revoke allowances instead of leaving broad payment access with an agent.

Security Model

Allowance is designed so agents spend with scoped authorization instead of receiving the human's real card. Approvals, limits, receipts, and audit trails are enforced by Allowance.
