Formal Semantics for Agentic Tool Protocols: A Process Calculus Approach

arXiv:2603.24747v2 Announce Type: replace Abstract: The emergence of large language model agents capable of invoking external tools has created urgent need for formal verification of agent protocols. Two paradigms dominate this space: Schema-Guided Dialogue (SGD), a research framework for zero-shot API generalization, and the Model Context Protocol (MCP), an industry standard for agent-tool integration. While both enable dynamic service discovery through schema descriptions, their formal relationship remains unexplored. Building on prior work establishing the conceptual convergence of these pa

Why this matters
Why now

The rapid deployment of large language model agents and their integration with external tools creates an immediate need for formal verification methods to ensure reliability and safety.

Why it’s important

Formal verification of agent protocols is critical for the robust and secure operation of AI agents, preventing failures and enabling their widespread adoption in sensitive applications.

What changes

The systematic development of formal methods for AI agent-tool interactions shifts the focus towards more reliable and verifiable AI systems, moving beyond ad-hoc integration.
