Works with
Your firm's memory, inside Cursor
Cursor can read your codebase. It cannot read the decision that shaped it — the paper that argued for the approach, the constraint a client imposed, the thing that was tried in 2023 and abandoned for a reason nobody wrote in a comment. Nemosyne connects that record over MCP.
How the connection works.
- Create your organisation and connect the sources where the reasoning actually lives — the document store, the tracker, the threads.
- Add the MCP endpoint to Cursor and sign in through OAuth as yourself.
- Ask why something is the way it is, and get an answer that names the document rather than guessing from the code.
What it is good for here.
- Decisions
- What was resolved, by whom, and on what stated rationale — from the minutes rather than from a commit message.
- Precedent
- The earlier cases that resemble this one, with what happened next.
- Constraints
- Commitments made to a client or a regulator that the repository has no way to know about.
- Contradiction
- Where two records disagree, both stay attached — so a stale design note does not quietly become the answer.
What the connection does not do.
It does not widen anyone's access: it hands back cited passages from the firm's documentary record, and the permissions on everything it read stay as they are.
What we enforce, and the limits we publish →Questions this raises.
- Is this a code index?
- No. It does not read your repository; it reads documents, records and threads. If your reasoning lives in a design document or a ticket, it can read that; if it only lives in the code, this is the wrong tool.
- Does it write anything back?
- Attributed writes are a tool an agent can call, and they land in the memory as statements with the person who made them attached. Nothing is written back into a source system.
- Can I connect it alongside other MCP servers?
- Yes. It is an ordinary MCP server and does not care what else is connected.
