Official MCP server by Mastercard to access their developer platform's documentation and API specifications. Suitable for developers wanting to add Mastercard API information retrieval to their workflows. Low risk as it involves no sensitive operations, but network dependency should be noted.

Why each score

Reliability 9/20: Evidence: the repository contains a TypeScript codebase with MCP SDK integration and an npm package named @mastercard/developers-mcp. The declared tools (get-services-list, get-documentation*, get-api-operation*) match the README surface. Deduction: static review only; the submitted files show no committed tests or CI execution artifacts covering key server paths, so the 12-point ceiling applies. Error handling, limits, and edge cases are undocumented; uncertainty yields 9.
Security and permissions 13/20: Evidence: no red-line issues found (no malware, credential theft, covert exfiltration, destructive operations, fabricated identity, or real tokens in install examples). The package is published on npm and traceable to the Mastercard GitHub org. Deduction: documentation does not disclose scope beyond fetching external documentation/API specs, credential handling, or confirmation flows (operations appear read-only, so no dangerous side effects, but least-privilege/confirmation guarantees are not explicit). No dependency security policy evidence, so full marks are not justified.
Maintenance 10/20: Evidence: the repository is not archived, has an MIT license, an npm release (0.1.7), a maintained manifest with a version, and open issues are tracked. Stars are treated only as discovery signals. Deduction: static evidence does not verify commit frequency, release cadence, dependency update practice, or a security response channel; governance gaps prevent a score above 10.
Documentation 12/20: Evidence: README covers installation via npx and npm, Node 18+, example code, and tool-level descriptions; separate READMEs for modelcontextprotocol and typescript are referenced. Deduction: no per-tool parameter reference, authentication details, rate limits, cost/quota limits, or troubleshooting section; data-flow/network behavior is only implied. Layered documentation exists but has hidden assumptions, so 12.
Setup experience 9/20: Evidence: setup is described as straightforward: run npx -y @mastercard/developers-mcp or install via npm, with a stdio connection example. Deduction: static review means no verifiable execution evidence (real CI/tests) exists among the supplied files; the README lacks step-by-step client configuration examples for mainstream MCP clients and does not explain optional env/auth configuration. Per the ceiling and uncertainty, setup is 9.

Fit and risk

What it can accessUses the network

Best for

Developers building AI assistants or agents that need to integrate with Mastercard Developers APIs.
Teams looking for quick access to Mastercard API documentation within their development environment.

Not for

Not suitable for users needing actual API calls or transactions; this server only provides information retrieval.
Not for generic documentation searches unrelated to Mastercard Developers.

Required permissions

No authentication or API keys required for the server itself, as it accesses only public documentation and API specifications.
Client requires ability to execute `npx` command.

Risks and side effects

Documentation and API specs may not be the most up-to-date since information comes from the public developer portal.
Dependent on network connectivity; server may not work if Mastercard developer portal is unreachable.
As a third-party extension, there could be undiscovered bugs or limitations.

Setup

Before you start

Runtime：Node.js 18+

Ensure Node.js 18 or higher is installed.
In your MCP client, configure the server with the command npx -y @mastercard/developers-mcp (or use the install_config above).
Alternatively, install the npm package @mastercard/developers-agent-toolkit in your TypeScript/JavaScript project and integrate it programmatically.

claude_desktop_config.json

{
  "mcpServers": {
    "mastercard-developers-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@mastercard/developers-mcp"
      ]
    }
  }
}

Shown for Claude Desktop. Other clients may use a different file or key (VS Code uses "servers") — the configurator below converts it.

.vscode/mcp.json

{
  "servers": {
    "mastercard-developers-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@mastercard/developers-mcp"
      ]
    }
  }
}

Goes in your project's .vscode/mcp.json (VS Code uses a "servers" key).

Terminal

claude mcp add mastercard-developers-mcp -- npx -y @mastercard/developers-mcp

Run it in a terminal; replace any <…> placeholders with your own values first.

Generate and validate client config

Check that it works

After configuring mastercard-developers-mcp (npx -y @mastercard/developers-mcp) in your client, the tool list should show the nine tools including get-services-list; calling get-services-list and receiving the Mastercard products/services list confirms the connection works.

Troubleshooting

Check Node.js version is >= 18.
Ensure network connectivity and that developer.mastercard.com is accessible.
Verify server command and arguments in the client configuration.
If using the npm package, ensure proper import and initialization.

Things to try

Once connected, you can ask your AI assistant things like:

List all available products and services on the Mastercard Developers platform.
Show me the OAuth 2.0 integration guide.
List all API operations in a Mastercard API specification with their HTTP methods.
Get the detailed parameter definitions and request/response schemas for a specific API operation.
