GlitterKill/sdl-mcp
SDL-MCP (Symbol Delta Ledger MCP Server) is a cards-first context system for coding agents that saves tokens and improves context.
Based on the SDL-MCP README, here's a technical summary: --- Implements a symbol-graph indexing system with a four-rung "Iris Gate Ladder" that escalates context precisely — Symbol Cards (~100 tokens with signatures and metadata), Skeleton IR (~300 tokens with control flow), Hot-Path Excerpts (~600 tokens for specific identifiers), and Raw Code (gated at ~2,000 tokens). Uses native Rust or Tree-sitter parsers across 12 languages and stores metadata in LadybugDB with confidence-scored dependency resolution that traces calls across imports and barrel re-exports. Exposes 35 MCP tools, 13 CLI commands, and an HTTP API for integration with Claude Desktop, Cursor, Windsurf, and other MCP-compatible coding agents.
Available on npm.
