Koskamo

honesty-mcp

An MCP server exposing eleven honesty-SDK kits as agent tools for checking citations, evidence, claims, and decisions. It provides tools for grounded-citation checking, evidence corroboration grading, trust/authenticity scoring, provenance-claim validation, and tamper-evident audit chains. The server is designed to be thin, using Zod input schemas to call unmodified exports from sibling kit repositories.
