Decision rule: use MCP when an agent needs to reach down into the world (database queries, file reads, API calls); use A2A when independent agents need to delegate work across boundaries they do not fully control; use both when the system has both vertical and horizontal needs.

UnverifiedPermissions granted to agents via MCP may involve write operations, system calls, and even access to sensitive data, not merely read-only queries.70% similarUnverifiedThe design adopts a separation of concerns: the Data Space handles governance and compliance, MCP handles protocol translation and tool exposure, and the LLM agent handles intent understanding and task orchestration.70% similarUnverifiedIrreversible operations (deleting data, sending emails, calling paid APIs), cross-system boundary operations, and decisions where agent confidence falls below a threshold are commonly listed as candidate scenarios requiring human confirmation.69% similarUnverifiedSetting permissions and boundaries at the tool layer enables fine-grained control over what an agent can and cannot access, reducing the risk of unauthorized operations or misuse.69% similarUnverifiedAssigning independent keys to agents allows the server side to distinguish between "direct user operations" and "agent-proxied operations" and apply different permission boundaries accordingly.68% similar
