### Description (declared)

# cypherwolf-mcp

**CypherWolf** revises Neo4j Cypher queries against a curated corpus of Neo4j
engineering precedent, returning compatibility-gated **precedent** options plus
the index/constraint validation gates to confirm before applying changes.

It ships as a single-tool MCP server (`revise_query`) that runs locally over
stdio and proxies to the CypherWolf HTTPS service. **Access is restricted to
`@neo4j.com` users.** The package holds **no** API key, **no** shared secret,
and **no** Aura credentials — all access control is enforced server-side via an
email gate plus a 30-day session token.

Get set up in about two minutes: **install → sign in → add to your MCP client →
`cypherwolf-mcp status` to confirm → ask for a rewrite.**

## 1. Install

CypherWolf is a standalone CLI, so install it with [pipx](https://pipx.pypa.io) —
it isolates the dependencies and puts the `cypherwolf-mcp` command on your `PATH`:

```bash
pipx install cypherwolf-mcp
```

Requires Python 3.10+. Dependencies are just `mcp` and `httpx` — no database
driver, no cloud SDKs.

Don't have pipx? Install it (`brew install pipx` on macOS, or
`python3 -m pip install --user pipx`) and run `pipx ensurepath`. On
Homebrew/externally-managed Python, `pip install cypherwolf-mcp` fails with a
PEP 668 error — pipx is the supported path. (A manual `pip install` inside an
activated virtualenv also works if you prefer.)

Upgrade later with `pipx upgrade cypherwolf-mcp`.

## 2. Sign in

Sign in once in a normal terminal with your Neo4j email:

```bash
cypherwolf-mcp auth
```

You will see the following disclosure, then be prompted for your email and a
6-digit code sent to it:

> This will email a 6-digit code to verify your @neo4j.com address. Your
> queries and the rewrites are saved to a Neo4j-internal folder under your
> email for internal use only.

The resulting session token is cached at `~/.cypherwolf/credentials.json`
(mode `0600`) and is valid for 30 days. After it expires — or if the token is
