How to use Claude Code with Nullprint

Q: Can I use it from another machine?

Yes, pass --daemon-url and NULLPRINT_API_KEY; reach the daemon over an SSH tunnel or private network, not the public internet.

Let Claude Code create, check and drive your Nullprint profiles through MCP.

What it is

Claude Code is Anthropic's coding agent for the terminal. With the Nullprint MCP server it can list, create, check up, start and stop your profiles, and browse inside them.

Set it up in Nullprint

Install Nullprint, sign in and keep the app running.
Install uv (or use Node.js 18+ and replace uvx nullprint-mcp with npx -y nullprint-mcp).

Connect Nullprint:

claude mcp add --scope user nullprint -- uvx nullprint-mcp

Check it with claude mcp list. You should see nullprint as connected. Inside a session, /mcp lists its 17 tools.
Start claude and ask: List my Nullprint profiles and tell me which are running.

Why they work well together

Every profile Claude opens keeps its own frozen fingerprint and proxy, so an agent never mixes accounts.
Check-up runs before launch, so Claude can tell you which profiles are not Consistent before it touches them.
Permanent deletion is not an MCP tool. The worst an agent can do is move a profile to the recycle bin.
