MCP Local Auditor & System Architect V2 is a dual-mode, zero-token-cost local engineering engine built on the Model Context Protocol (MCP). It dynamically switches between Production Code Auditor and System Architect & Strategist roles via local models in LM Studio, backed by a fast AST security filter, dual data sinks, and a real-time Discord notification daemon. The engine routes tasks automatically based on the payload structure passed to `audit_submission`.

In Code Auditor Mode, it audits incoming implementations against 10 strict defensive engineering rules, including logic and edge conditions, resource leaks and performance, defensive boundaries, and a deterministic contract. A sub-millisecond AST Sentinel rejects Python syntax errors and blocks high-risk calls such as eval, exec, os.system, and subprocess before hitting the LLM.

In System Architect & Strategist Mode, it generates system designs for technical prompts without code, including component topologies, preemptive risk modeling, and master execution plans. It records execution metrics into SQLite and exports atomic JSON telemetry suitable for DPO fine-tuning datasets. A background daemon monitors audit output files in real time and pushes structured embeds directly to Discord.
