Why A2A and MCP Matter for CPaaS Providers
Agent-to-Agent (A2A) and Model-Context Protocol (MCP) are highly relevant for CPaaS providers who are building intelligent, automated, and scalable communication platforms, as the workflows involve access to data sources (internal and external) and invocation of 3rd-party vendor capabilities beyond organizational boundaries.
What is A2A?
In simple words, A2A Protocol allows AI agents to talk and coordinate with each other. Google has developed this open protocol collaborating with more than 50 technology providers.
What is MCP?
In simple words, MCP is a structured method for delivering all necessary context (memory, tools, goals, and input) to a language model in a standardized, reproducible way before execution. Anthropic developed the MCP protocol and it has been adopted by Open AI as a standard.
A2A vs MCP Quick Comparison
Why are they relevant for CPaaS vendors?
MCP ensures every interaction whether on SMS, WhatsApp, or voice is handled by an LLM with the right context (customer history, channel, preferences), leading to accurate, compliant, and personalized responses.
A2A enables coordination between specialized agents (planner, summarizer, notifier, verifier) to automate and scale complex workflows like customer support, lead routing, and escalation handling across channels.
Use Cases: CAMARA APIs, Messages API and Voice API
Summary
A2A and MCP transforms the CPaaS APIs from just being transactional tools into intelligent and autonomous communication systems.
