Formal Semantics for Agentic Tool Protocols: A Process Calculus Approach

📰 ArXiv cs.AI

Researchers propose a process calculus approach to formalize semantics for agentic tool protocols, enabling verification of agent interactions with external tools

advanced Published 27 Mar 2026

Action Steps

Define a process calculus framework for modeling agent-tool interactions
Formalize the semantics of agentic tool protocols using the process calculus approach
Verify the correctness of agent protocols using the formalized semantics
Apply the framework to existing paradigms such as Schema-Guided Dialogue (SGD) and Model Context Protocol (MCP)

Who Needs to Know This
