MIDPLANE_TOKEN secret required env
A token from `midplane token`, verified at start and on every call. It stays in this entry, so give it a --ttl (seconds) as long as the entry should work: the default is an hour.

Common questions

Is Midplane safe?

It passed 3 of 3 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?

You need to fill in: MIDPLANE_TOKEN

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 yesterday, and the latest version (0.26.1) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

midplane

The Midplane gateway: an MCP server that sits between AI agents and your Postgres databases. Every statement an agent sends is parsed, checked against a policy and recorded before it runs. Agents get table access you grant, masked columns, writes held for a person's approval, and containment once they read untrusted content. It runs next to your databases; nothing connects in to it but agents.

npx midplane --version

Node 24.16 or newer.

Local mode (midplane local): the policy lives in a YAML file and tokens come from midplane token. Try it with the quickstart.
Linked mode (midplane gateway): policy, identities, approvals and a query log come from Midplane Cloud, over a link the gateway opens. midplane setup makes one: it asks for each database's connection string, tests it, writes the gateway's folder, enrolls and starts it.
The audit log stays on the gateway's disk, hash-chained: midplane audit export and midplane audit verify.

Documentation: https://midplane.ai/docs. The image: ghcr.io/midplaneai/midplane. Both are signed: see verifying a release.
