# Mastercard Developers — AI Connector Mastercard Developers publishes 9 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/mastercard-developers/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # Mastercard Developers Live Mastercard API specs and integration guides for coding agents Listed in Claude · 9 published tools · Verified partner [Claude connector docs](https://developer.mastercard.com/platform/documentation/agent-toolkit/) [developer.mastercard.com](https://developer.mastercard.com/) Overview ## What Mastercard Developers does This connector points at Mastercard's developer platform rather than at any payment account. It gives an assistant live access to the API catalogue: service listings, endpoint specifications, request and response schemas, documentation pages, and authentication guides covering OAuth 1.0a, OAuth 2.0 and the Open Finance scheme. The reason the publisher gives is currency. A model writing integration code from training data alone reproduces whatever the specification looked like at its cutoff, whereas these calls fetch the current text. Nine tools are published and nine answered. No cardholder or merchant data passes through the connector. ### Who it is for Developers integrating Mastercard APIs who want specifications fetched rather than recalled. ### Tool surface All nine tools are \`get-\*\` reads over documentation and specifications: \`get-services-list\` and \`get-documentation\` for orientation, \`get-documentation-section-content\` and \`get-documentation-page\` for text, \`get-api-operation-list\` and \`get-api-operation-details\` for schemas, plus three named integration guides. Nothing writes, and nothing touches a Mastercard account. Availability ## Where Mastercard Developers is listed Mastercard Developers is listed in the Claude connectors directory only. Mastercard has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Mastercard Developers publishes 9 tools to Claude. That is a mid-sized surface: 41.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Finance publishes 12, so this one sits 3 tools below its bucket's median, 95th of 159. It falls in the 7-10 tools band, which holds 14.6% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 9 tools, matching the 9 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `get-services-list` - `get-documentation` - `get-documentation-section-content` - `get-documentation-page` - `get-oauth10a-integration-guide` - `get-oauth20-integration-guide` - `get-openfinance-integration-guide` - `get-api-operation-list` - `get-api-operation-details` Mastercard Developers publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Mastercard Verification Verified partner (37.8% of the Claude directory) Filed under Financial Services Endpoint `https://developer.mcp.mastercard.com/` Documentation [Publisher setup docs](https://developer.mastercard.com/platform/documentation/agent-toolkit/) Published tools 9 · 7-10 tools band Depth rank in Finance 95 of 159 Snapshot August 2026 Mastercard Developers carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server. In the publisher's words ## How Mastercard describes it > Connect your AI assistant to Mastercard's developer platform. This server gives AI agents live access to Mastercard's full API catalog, including endpoint specs, request and response details, authentication guides for OAuth 1.0a, OAuth 2.0, and Open Finance, and structured documentation with code samples. Agents can discover services, retrieve integration guides, and generate accurate code without relying on stale training data.
