Use the Mastercard Developers connector safely and well

Guides an AI assistant through reading Mastercard's developer documentation: confirming scope, choosing the right documentation or integration-guide tool, and keeping answers sourced. It is read-only and will not change anything on your account.

Use it when

  • You want to know which Mastercard API fits your payment or banking feature.
  • You are unsure whether your integration uses OAuth 1.0a, OAuth 2.0 or Open Finance.
  • A documentation lookup returned nothing and you want to know what to try next.

Tools it uses

  • get-services-list
  • get-documentation
  • get-documentation-page
  • get-documentation-section-content
  • get-api-operation-list
  • get-api-operation-details
  • get-oauth10a-integration-guide
  • get-oauth20-integration-guide
  • get-openfinance-integration-guide
Example

Which Mastercard API should I use to send a payment from my app, and which auth model does it need?

I'd start with the service list to find the payment product, then pull the OAuth integration guide that matches your setup. I'll keep the answer to the sections I actually read and flag anything the docs don't cover, rather than guessing parameter names.

Mastercard Developers API operation lookup

Finds one specific Mastercard API operation, reads its details and produces a short reference card covering purpose, parameters and what to verify. It marks anything the docs do not establish rather than guessing.

Use it when

  • You need the endpoint for one Mastercard API action and want its parameters.
  • You want a reference card to paste into a ticket before writing code.
  • You are not sure which operation matches a resource and need a short candidate list.

Tools it uses

  • get-services-list
  • get-api-operation-list
  • get-api-operation-details
  • get-documentation-page
  • get-documentation-section-content
  • get-oauth10a-integration-guide
  • get-oauth20-integration-guide
  • get-openfinance-integration-guide
Example

Give me a reference card for the Mastercard operation that creates a payout, with its parameters and anything I should verify first.

Operation: create payout (service: the payouts API, POST /payouts). Auth model: stated in the integration guide, not in the operation details, so confirm it there. Parameters: the request body fields are listed as documented, with two marked required. Verify before use: confirm the product is onboarded in your account and whether this runs in sandbox. Not established: rate limits and field length limits are not stated in the operation details.

Choose a Mastercard API integration path

Works out which auth model fits your use case (OAuth 1.0a, OAuth 2.0 or Open Finance), pulls the matching integration guide, and returns an ordered build path with the prerequisites to check first. It only reads documentation and does not change any account settings.

Use it when

  • You are starting a new Mastercard API integration and need to know which auth model to use
  • You want the setup steps in build order, with credentials checked before any code
  • Your integration fails at the first call and you want to rule out auth and environment setup

Tools it uses

  • get-services-list
  • get-oauth10a-integration-guide
  • get-oauth20-integration-guide
  • get-openfinance-integration-guide
  • get-api-operation-list
  • get-documentation
  • get-documentation-page
  • get-documentation-section-content
Example

I want to pull bank account data with consent from my app. Which Mastercard auth model applies and what order should I build in?

This looks like a consent-based account-data flow, so Open Finance is the likely model, with OAuth 2.0 as the token layer underneath. Check these first: a sandbox project, registered redirect URIs and the consent scope. Build order: get a token in sandbox, make one read-only account call to confirm auth, then add the consent flow before any data retrieval.

How Mastercard Developers skills work

  1. Connect Mastercard Developers

    The Mastercard Developers MCP server gives the agent its tools.

  2. Ask in plain words

    “Give me a reference card for the Mastercard operation that creates a payout, with its parameters and anything I should verify first.” Each SKILL.md says when it applies, so only the one that fits is loaded.

  3. Approve any change

    The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install Mastercard Developers skills

In RevampKey the skills install themselves when you connect Mastercard Developers. In other tools each skill is one folder with a SKILL.md file, and you also need the Mastercard Developers MCP server connected there.

About 1 minute · nothing to copy

  1. Download RevampKey for Mac, Windows or Linux and sign in.

  2. Open Connectors and connect Mastercard Developers. All 3 skills come with it and stay up to date; they go away when you remove the connector.

Mastercard Developers skills FAQ

What is a Mastercard Developers agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Mastercard Developers skill describes one job, which Mastercard Developers tools to use in which order, what to check first and when to stop and ask you.

Do the Mastercard Developers skills change anything on their own?

3 of the 3 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Mastercard Developers.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Mastercard Developers; elsewhere you copy the folders into your project or skills directory.

Do I need the Mastercard Developers MCP server too?

Yes. The skills tell the agent how to do the work; the Mastercard Developers MCP server gives it the tools to do it. The Mastercard Developers MCP setup guide covers every client.
