Mastercard Developers MCP is a Model Context Protocol (MCP) server: Access Mastercard Developers APIs, documentation, and API specifications through MCP. In practice that means any MCP-compatible AI assistant can call Mastercard Developers MCP's tools directly — the model decides when to use them in a conversation or agent run.
It runs locally: the npm package @mastercard/developers-mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.1.0, published under the MIT license, with source at Mastercard/developers-agent-toolkit on GitHub, where it has earned 55 stars.
Mastercard Developers MCP is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
