Common questions
Is Lupin safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

Lupin
An MCP server for the Revenue Alignment Engine: an opportunity ledger and capability registry with lane-scoped access. Opportunities live in one of two lanes — Qompass (sfw) or NTRanch (nsfw) — and a caller scoped to one lane can never see the other lane's entries.
Lupin is a single Rust binary. It speaks MCP over stdio (NDJSON JSON-RPC) to the client and works on plain files under a data root — no database, no network listener. It is the ledger side of the estate's revenue pipeline; the research-feed server phaedrus drafts candidates into it.
How it runs
- Data root (ledger, capability registry, scan inbox):
--rootor theREVENUE_ROOTenvironment variable (default~/workspace/revenue-alignment-20261019). - Lane scope:
--lane-scope operator|sfw(defaultoperator). The operator scope sees both lanes; ansfw-scoped caller can never seensfwentries. - Read-mostly by design: the only write files a *candidate* into the scan inbox (
opportunity_submit). The validated ledger is never written by this server, andcapability_matchis advisory only — it never auto-aligns an opportunity.
Tools
| Tool | What it returns |
|---|---|
capability_list | The capability registry (the alignment vocabulary); lane scope enforced |
capability_match | Advisory keyword match of free text against capabilities; never auto-aligns |
opportunity_get | One ledger entry by id, including its raw block |
opportunity_list | Ledger opportunities, optionally filtered by status; lane scope enforced |
opportunity_submit | File a candidate into the scan inbox; never writes the ledger |
pipeline_summary | Counts by status/lane plus parse health — the value-demonstration view |
