Atlas next to your agent's built-in context.
Claude Code and Cursor are excellent coding agents. Atlas is a persistent local memory layer they can both read from.
| Capability | Claude project context | Cursor built-in context | Atlas |
|---|---|---|---|
| Persistent repo memory across sessions | Session/project scoped | Session/workspace scoped | Yes - the local index persists until you rescan |
| Repository indexing runs locally | Context handled by the tool | Codebase indexing; check Cursor docs for current details | Yes - indexing never leaves your machine |
| Answers with cited files | Sometimes, from what is in context | Sometimes, from retrieved context | Every answer lists grounded files |
| Dependency graph of the repository | No | No | Resolved import graph with hubs and cycles |
| Impact analysis | Ad-hoc, model-driven | Ad-hoc, model-driven | Deterministic, from the resolved graph |
| MCP server other tools can call | Claude consumes MCP | Cursor consumes MCP | Atlas is the MCP server |
| Works across Claude Code, Cursor, and Codex | Claude only | Cursor only | One index, three agents |
Built-in behavior of other tools changes over time; check their docs for current details. This table describes how Atlas complements them.
Limits
No fake certainty.
Numbers are self-measured on one Windows development machine; your hardware will differ.
The 50-scenario suite runs against a reference repository we built, not a random sample of OSS projects.
Large monorepo indexing is slower and is an active work item.
Retrieval quality is not the same as end-to-end task success with a coding agent.
