Scout-AST 🎯

Context-compression and automated verification middleware exposed via an MCP (Model Context Protocol) server.

Scout-AST strips down source code into hyper-dense structural skeletons (graph.json < 20KB) using local Tree-Sitter parsing. It integrates with developer tools (Cursor, Claude Code, Windsurf) via MCP, and runs micro-cost verification checks using a Cloud Critic Agent (DeepSeek V4 Flash) with 98% prompt context caching discounts.

Features

• Local Parser ($0 Compute Cost): Uses Tree-Sitter to generate structural skeletons containing only function signatures, imports, class hierarchies, and file relationships.
• MCP Server Layer: Integrates directly with Cursor, Claude Code, and Windsurf via FastMCP.
• Cloud Critic Gateway: Validates proposed code diffs against the structural graph before developer application.
• Zero-Burn Economics: Achieves 98% prompt caching discounts via Static AST Prefix + Dynamic Diff Tail prompt structuring.
• Enterprise Security: Air-gapped code delivery, Tailscale mesh compatibility, and gVisor sandbox readiness.
