An MCP server that enforces fail-closed deterministic checks, independent refute-first review, and tamper-evident hash-chained receipts for AI agent outputs before claiming completion.
An MCP server that acts as an authorization gateway between an AI agent and external systems, deterministically refusing actions that exceed granted authority and sealing every decision into an auditable chain of custody.
MCP server that gates agent tool calls by normalizing intent, denying unknown/unattended destructive actions, and requiring HITL prove approval for high-risk operations. It maintains an append-only hash-chained Action Ledger and exposes gate_check and ledger_verify tools without ever executing tools.
