The Webmcp Paradox Theorem

The WebMCP Paradox Theorem formalizes a structural law governing the relationship between execution efficiency, process visibility, human operational understanding, and drift accumulation within agent‑mediated web environments. As callable execution replaces human navigation, procedural exposure contracts, producing a systematic decline in what users can know about the systems they rely on. The theorem reframes the agentic web not as a usability improvement but as a transformation of epistemic conditions: efficiency increases while legibility decreases. Through definitions, axioms, and structural operators, the paper models how agentic autonomy compresses intermediate states, concentrates operational knowledge within agents, and generates epistemic asymmetry between visible outcomes and actual operations. The framework positions the WebMCP Paradox as a foundational law of the emerging agentic substrate.
