What it does

Ontology Atlas is an open-source desktop app that shares codebase context with Claude Code or Codex over MCP from a Markdown vault. You inspect recorded capabilities, evidence, and unknowns, then decide which proposed meaning changes to keep. A signed macOS build and an unsigned Windows beta are offered, with no Atlas backend.

Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.
