Aperion Shield MCP

A local, open-source MCP guardrail that intercepts tool calls to block destructive actions like DROP TABLE or rm -rf. It evaluates calls against adaptive safety rules, scans tool catalogs for poisoning, and provides pre-install audits and OS-level sandboxing without requiring cloud connectivity or telemetry.
