Authometry is an OAuth 2.0 and OpenID Connect authorization platform built so you can see exactly what happened on every request. Each authorization gets a trace with secrets redacted and an explanation of what went wrong and how to fix it.

It covers the standard flows (Authorization Code with mandatory PKCE, rotating refresh tokens with reuse detection, Client Credentials, Device Authorization) plus the agent side of auth: registered agent identities, DPoP-bound tokens, delegation grants, and token exchange.

Everything can be managed from the dashboard, from Git as configuration as code through a Homebrew-installable CLI, or by an AI client through a built-in, OAuth-scoped MCP server.
