Formal Semantics for Agentic Tool Protocols: Process Calculus Approach to MCP and SGD Verification (arXiv 2603.24747)
arXiv·medium signal
New paper provides formal mathematical verification of agent-tool integration protocols, examining both Schema-Guided Dialogue (SGD) and Model Context Protocol (MCP) paradigms through process calculus. This is the first rigorous formal semantics treatment of MCP, enabling mathematical proofs about protocol correctness, deadlock freedom, and security properties. For builders deploying MCP at scale, formal verification moves agent reliability from 'seems to work' to provably correct.
