FRAYWICK is a public watchtower for agent tools. Every hour it reads the tool definitions of the public MCP servers in the official registry, popular Agent Skills (SKILL.md) and their npm/PyPI package metadata, hashes each one (RFC 8785 canonical JSON, keccak256) and stamps one merkle root per hour on Robinhood Chain (ToolAnchor; Sourcify exact match; unaudited). When a tool's description or schema changes, the diff is labelled cosmetic, behavior or suspicious, and anyone can prove when it changed: recompute any row in the browser, run the open-source CLI, or ask the read-only MCP endpoint. It routes nothing, hosts nothing and runs no third-party code. Auth-only servers are metadata only. The token has no fee, pot or burn mechanics; creator tax 0 %. Independent. Not affiliated with Anthropic, the MCP project or Robinhood. fraywick.xyz
