The skills field of the Agent Card is mostly natural language descriptions plus a few examples, lacking formal constraints like JSON Schema on parameter types, required fields and value ranges, which is the main obstacle when wrapping A2A agents as MCP tools.

UnverifiedMCP's tool schema requires field-by-field definition of types and constraints, and the calling model generates structured parameters accordingly; the A2A side lacks equivalent formal information, so the adaptation layer can only rely on inference or manually supplementing the schema.74% similarVerifiedEach tool in MCP has a strict JSON Schema description, including the name, functional description, and parameter specifications69% similarUnverifiedAnthropic提出的代码执行方案将MCP工具暴露成TypeScript代码API，让Agent写代码来调用工具而非直接调用66% similarUnverified在资源受限的MCU上，通过函数指针、结构体封装等C语言特性即可实现清晰的模块边界和分层架构65% similarPartially VerifiedThe description field in the tool metadata that an MCP server exposes to clients is essentially a natural language instruction aimed at the model, rather than documentation aimed at human users, and typically has no structured validation or input filtering.64% similar
