bluerock vs Sentinelgate

bluerock: BlueRock is a lightweight runtime security sensor for Python MCP servers. It monitors MCP tool calls, resource access, session lifecycle, and module imports with zero code changes, emitting structured NDJSON events for every operation.; Sentinelgate: SentinelGate is a self-hosted, container-native, zero-lock-in proxy that intercepts every action of an AI agent before it executes, applying deterministic rules to block unauthorized tool calls, shell commands, and file operations. It provides a full audit trail, content scanning, and session-aware policies, and works with any MCP-compatible client or sandbox.
