Preflight

Preflight is a Model Context Protocol (MCP) server that integrates with Claude Code development environments to prevent wasted compute on ambiguous or vague prompts. By analyzing prompts and session history, it classifies each instruction, triggers the appropriate clarification or verification workflows, and maintains semantic search across all session data. Preflight is ideal for developers and teams who want to improve prompt clarity, reduce correction cycles, and optimize token usage in AI-augmented coding projects.
