ContextAtlas

ContextAtlas is an MCP server that gives Claude Code a curated atlas of your codebase — fusing LSP-grade structural precision with architectural intent extracted from your ADRs, docs, and git history, delivered to Claude at query time in on demand single-call context bundles. One of the many problems it actually solves: when three developers on the same team use AI agents independently, each agent makes locally-rational decisions without knowing what the others have already decided. You end up with three devs making four conflicting choices in the same sprint and nobody catches it until something downstream breaks. ContextAtlas’s atlas.json is a committable team artifact that lives in your repo, so every agent on every machine reads from the same architectural ground truth. Beyond alignment, the efficiency story: measured 45-72% token reduction with zero quality regression on architectural prompts across the hono / httpx / cobra benchmark suite, paired-t methodology with pre-registered thresholds. Agents stop burning tokens rediscovering structure your team already documented. Supports TypeScript, Python, Go, and Ruby. Skills path for Claude Code subscribers (no API key); CLI path for API users.
