  • get_spending_summary - See how much has been spent so far against the configured limits (daily, weekly, monthly, and total), including any account-wide limit that applies across all of an account's agents.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http authoryze 'https://authoryze.ai/api/mcp' --header 'Authorization: <Bearer token using your agent API key (format: Bearer <key>). Not needed when using OAuth — Claude Desktop, Claude.ai, and ChatGPT authenticate via OAuth automatically.>'
JSON configuration (Claude Desktop, Cursor, VS Code)

Authoryze MCP Server

Authoryze gives your AI agent a spending limit. It lets you hand an agent a payment method without handing it your card: you define what it can buy, from which merchants, and up to what amount, and every purchase request comes to you for approval before a single-use virtual card is issued. It is built on Visa Intelligent Commerce and Mastercard Agent Pay, and is currently available for US-issued cards. Authoryze is a remote MCP (Model Context Protocol) server that works with Claude, Claude Code, ChatGPT, Cursor, Windsurf, and any MCP-compatible client.

Installation

OAuth-capable clients such as Claude and ChatGPT need only the endpoint:

{
  "mcpServers": {
    "authoryze": {
      "url": "https://authoryze.ai/api/mcp"
    }
  }
}

Clients that don't support OAuth, such as Claude Code, Codex, and custom frameworks, authenticate with a static agent API key as a bearer token:

{
  "mcpServers": {
    "authoryze": {
      "url": "https://authoryze.ai/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Tools

  • request_purchase - Ask to make a purchase from a specific merchant, for a specific amount, with a reason. The request either gets approved automatically, gets sent to the account owner for approval, gets denied with a reason, or fails in a way that's safe to retry.
  • check_status - Look up what happened to a purchase request: approved, denied, still waiting on approval, or failed. Doesn't reveal any card details itself.
  • get_spending_summary - See how much has been spent so far against the configured limits (daily, weekly, monthly, and total), including any account-wide limit that applies across all of an account's agents.
  • retrieve_card - Once a purchase is approved, get the actual card number, expiry, and security code to complete the purchase. This can only be done once per approved purchase; the details are shown a single time and can't be retrieved again.

Requirements

Authoryze is available for US-issued cards only. International support is pending issuer coverage on the agentic token programs.

Authentication requires either OAuth 2.1 with PKCE (S256) and Dynamic Client Registration, or a static agent API key used as a bearer token.

Frequently asked questions

What is Authoryze?

Give your AI agent a spending limit: approval controls and single-use virtual cards.

How do I install Authoryze?

It runs as a remote server. In Claude Code: claude mcp add --transport http authoryze 'https://authoryze.ai/api/mcp' --header 'Authorization: <Bearer token using your agent API key (format: Bearer <key>). Not needed when using OAuth — Claude Desktop, Claude.ai, and ChatGPT authenticate via OAuth automatically.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Authoryze need an API key?

Yes. It expects Authorization, which you set in its configuration.

Is Authoryze open source?

Its code is public on GitHub, but the repository does not declare a standard license.

Who maintains Authoryze?

It is published by kevinfee3. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
