Short summary

MCP and A2A protocols standardize how AI agents connect to financial tools and coordinate with each other, reducing integration complexity from N×M to N+M connections. Backed by IMF research and major AI providers, these standards are becoming critical infrastructure for banks to meet DORA compliance. They enable automation of credit decisions, fraud detection, and regulatory reporting at scale.

  • MCP connects agents to financial data sources; A2A enables vendor-agnostic agent coordination
  • Reduces integration debt: 15 agents × 40 data sources = 600 APIs → 55 MCP/A2A connections
  • Emerging standard adopted by OpenAI, Anthropic, PayPal, and major banks for DORA/EU AI Act compliance

Generated with AI, which can make mistakes.
