MCP Reliability Sidecar Slashes Harmful Events Across 200 Agent Runs
FewScarcity6957 · reddit · 2026-07-31
The author developed Agent Enhancer, a free MCP reliability sidecar requiring no API key, and published benchmark results from 200 runs.
- Safety Improvement: Harmful events (e.g., duplicate changes, conflicting actions, over-limit attempts) dropped from 26 to 2.
- Higher Completion: Verified task completion increased from 82.5% to 98.75%.
- Low-Risk Efficiency: Across 20 low-risk runs, the tool was correctly skipped, resulting in zero remote calls.
The trade-off is that protected risk scenarios consume more time and tokens. It is currently compatible with ChatGPT, Claude, generic MCP clients, and offers Agent Skills for coding tools like Codex.
