About Proof Holdings
Proof Holdings is an MCP server published by proof.holdings. One API, all things verified — control, delegation, human approval, anti-impersonation.
It runs on your own machine: your AI client starts it from the npm package @proof-holdings/mcp-server at version 1.7.1, or you can connect to the hosted version instead.
It asks for one secret: PROOF_API_KEY. Give it a key with the least access that still works.
Version 1.7.1 was published on 26 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 10 automated checks on the registry entry and the package code: 7 pass, 1 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
PROOF_API_KEY | No | Yes | Proof Holdings API key (Bearer). Optional: without it the server runs in public mode, where account creation, login and public verification tools work and every other tool asks for a key. Create one in the dashboard at https://proof.holdings. Or run `npx @proof-holdings/mcp-server login` in a terminal: it signs in, confirms on a second channel and saves a key in ~/.proof-holdings/credentials, which the server uses when this variable is unset (this variable wins when set). Either is read at startup and has no runtime setter, so restart the server after logging in. |
PROOF_BASE_URL | No | No | API base URL. Defaults to https://api.proof.holdings. |
