Gurusup Brain is building the company memory every AI agent can trust.
Available as a remote MCP server for Claude Code, Codex, Cursor and any MCP client.
Manifesto
Useful AI runs on context that keeps learning. Models change every few months, open models keep growing, and your team already uses more than one: Claude in the terminal, ChatGPT in the browser, Cursor in the editor. Your company's memory can't live inside any of them. It has to sit apart from the model provider, speak an open protocol and work with any model, any harness and any use case.
So we built the hard infrastructure of a company memory that scales: ingestion that stays current, claims that keep their source and owner, a graph of explicit relationships that grows with every source, permissions checked on every chunk, and a sense of time, so the answer in force wins over the old one.

How it works
Not one vector search. Similarity finds candidates, explicit relationships keep the meaning, and permissions are checked before anything is ranked.

Build vs buy
An internal RAG is easy to build. Then you maintain it forever.
| Build vs buy | Build it | Gurusup Brain |
|---|---|---|
| Ingestion | Connectors, parsing and re-sync jobs | Captured with provenance, new activity flows in |
| Freshness | Re-index jobs and version tracking | Checksums: only what changed is reindexed |
| Permissions | ACL sync per source, filtered after the fact | Per chunk, checked before ranking |
| Conflicts | Ranking picks a winner, silently | Linked and flagged, never overwritten |
| Retrieval | One vector index, tuned by hand | Lexical, vector, claims and graph, reranked |
| Ownership | Who to ask lives in someone's head | Every claim keeps its source and owner |
| Security | Auth, API keys and audit to build | OAuth 2.1 with PKCE, no keys to leak |

Why it scales
- ›Cost per question stays flat, no matter how many tools sit behind it.
- ›Once your data is indexed, one more question adds almost nothing.
