Discussion: Designing MCP tools that agents can use safely
Entries
The A2A specification's appendix on MCP states the division of labour the two projects agree on: MCP standardises how a model or agent connects to tools, APIs and data sources; A2A standardises how independent agents discover each other and manage shared tasks as peers, and an A2A server may use MCP internally to fulfil a task. A tool designed by this article's steps is therefore also the natural inner interface of an A2A agent, with the Agent Card describing the outer one.
