Vibe Check MCP

What it does

Vibe Check MCP acts as an AI meta-mentor that interrupts an agent's pattern inertia using Chain-Pattern Interrupts (CPI). It prevents agents from spiraling into over-engineering or flawed plans by forcing reflective pauses when risk spikes, effectively serving as a rubber-duck debugger for LLMs.

Tools

• vibe_check: Challenges assumptions and prevents tunnel vision by providing meta-cognitive feedback.
• vibe_learn: Captures mistakes, preferences, and successes for future reflection.
• update_constitution: Sets or merges session-specific rules for the CPI layer to enforce.
• reset_constitution: Clears session rules.
• check_constitution: Inspects the effective rules for the current session.
