# Announcing Mastercard’s Agent Toolkit: Accelerate API Integration With AI
source: https://developer.mastercard.com/blog/agentic-toolkit/index.md

Authors: Lisa Bongiovi. The way developers build software is undergoing a profound transformation. AI agents are no longer experimental, they're essential. With 84% of developers now using AI tools in their workflows and nearly half relying on them daily, the shift toward agentic development is accelerating. Yet, many developers still face friction when integrating complex APIs into their applications. Mastercard recognizes this challenge and the opportunity it presents. That's why we're introducing the Agent Toolkit on Mastercard Developers -- a Model Context Protocol (MCP) server that gives AI development tools direct access to our documentation. This toolkit is designed to meet developers where they are: in AI-native environments, using conversational interfaces to build, test, and deploy financial applications faster and more intuitively than ever before. Our goal is simple: to make Mastercard's APIs as accessible and actionable as possible for our customers. By bridging the gap between AI agents and our comprehensive API ecosystem, we're enabling developers to move from documentation-driven workflows to intelligent, conversational development, unlocking speed and innovation Install and Configure the Agent Toolkit The agent toolkit integrates with any AI development tool that supports the Model Context Protocol (MCP). One-Command Installation for Popular AI Tools Claude Desktop users: claude mcp add mastercard-developers -- npx -y @mastercard/developers-mcp Other development environments: npm install @mastercard/developers-mcp MCP Configuration Setup Add the toolkit to your MCP configuration file: { "mcpServers": { "mastercard-developers": { "command": "npx", "args": \["@mastercard/developers-mcp"\] } } } What You Get After Installation Your AI agents gain access to: Complete API documentation for every Mastercard service Up-to-date reference materials and integration guidance Real-time access to current API specifications and requirements Comprehensive troubleshooting resources for common integration challenges Sandbox environment information for safe testing and development Real-World Examples Product Discovery Question "I'm building a lending platform and need to verify applicant income - but I want to make sure it's a great user experience. Which Mastercard product can help me do this?" Technical Implementation Question "I'm working with Mastercard Send, and I want to know the endpoint that creates a funding transfer from a funding account." Transform Your Development Workflow The Agent Toolkit changes how developers build financial applications. Research from the 2025 Stack Overflow Developer Survey shows that while 69% of AI agent users report increased productivity, only 31% of developers currently use AI agents at work. The Mastercard Agent Toolkit addresses these concerns by providing Access to relevant APIs in minutes through conversational queries Current documentation and specifications for reliable implementation guidance Comprehensive integration information including error handling and security requirements Up-to-date API references that your AI tools can use for accurate suggestions This shift moves development from traditional documentation-driven workflows to AI-native, conversational development processes that aims to provide developers with accurate, current information.
