How it works
From raw repository to persistent memory.
Atlas turns local source into a validated map that survives fresh agent sessions.
Open a local repository
Atlas reads the selected folder on your machine. Repository contents are not uploaded during indexing.
Parse files and imports
The built-in 18-file sample indexes in ~4s; larger repos depend on hardware and size.
Build graph evidence
Modules, symbols, import paths and evidence rows become a dependency map the app can validate.
Persist memory
Fresh sessions restore the saved scan in 8–11ms when the repository signature still matches.
Connect agents
Claude Code, Cursor and Codex use the same 18-tool MCP surface.
Return cited context
Atlas returns cited context in 1–30ms after indexing — cited files rather than model guesses.
Install path
Start with the Windows app.
The public site does not change the download architecture: the installer route and GitHub release verification remain the source of truth.
Windows release
Atlas-Setup-1.0.5.exe · v1.0.5
No signup required. Windows SmartScreen may warn until the installer is signed.
Next
Connect the agents you already use.
Atlas writes local MCP config for supported agents only when you explicitly connect from the desktop app.
- 01
Claude Code
Use Atlas as an MCP server from your Claude workflow.
- 02
Cursor
Reuse the same local repository index inside Cursor.
- 03
Codex
Give Codex cited repository context for planning and debugging.
