SDL-MCP (Symbol Delta Ledger MCP Server) is a cards-first context system for coding agents that saves tokens and improves context.
SDL-MCP is a Model Context Protocol (MCP) server that transforms codebases into queryable, versioned knowledge systems for AI agents. It indexes symbols and dependencies into a SQLite-backed ledger, enabling efficient, precise context retrieval, delta analysis, and policy-gated code access.

Good for large codebases where context management is the bottleneck.

Cards-first context system for code is a novel approach to codebase understanding.

Symbol tracking with delta awareness is more efficient than full re-indexing.

The ledger concept makes code changes auditable in a way raw git diffs don't.
