ProvenanceGuard: Source-Aware Factuality Verification for MCP-Based LLM Agents
Consensus Brief
ProvenanceGuard is a new verification layer designed to enhance the factuality of answers generated by Model Context Protocol (MCP) agents by ensuring that claims are attributed to the correct sources. It addresses the issue of cross-source conflation, where a claim may be true but incorrectly attributed to a source, which can lead to misinformation in sensitive contexts like healthcare. The system was tested on medical agent outputs, achieving high accuracy in identifying correct sources for claims.
What Changed Since Last Update
ProvenanceGuard introduces a source-aware verification mechanism that preserves source identity throughout the answer generation process, unlike previous systems that pooled evidence without maintaining source attribution.
