Alter is the authorization layer that sits between your AI agents and every OAuth credential they need. Scope it, rotate it, revoke it — without rewriting your agents.
When a human logs in via OAuth, there's one token, one session, one audit trail. When an AI agent runs 400 tasks a day across GitHub, Slack, and Salesforce, you get 400 tokens with no lifecycle management, no scope enforcement, and no revocation path.
AI agents create OAuth tokens on-demand and never clean them up. After 90 days, no one knows which tokens are active or what they have access to.
Standard OAuth scopes are too coarse for agents. An agent that needs read-only GitHub access often gets full repo write — because that was easiest to set up.
When a compromised agent uses a leaked token, the audit log shows "GitHubApp authorized" — not which agent, which task, or which human triggered it.
Alter proxies every OAuth request your agents make. It mints short-lived tokens, enforces minimum-privilege scopes, and builds an immutable audit log keyed to the agent run — not the app.
Point each AI agent at Alter's credential proxy endpoint. No SDK required — Alter speaks standard OAuth 2.0 so existing agents connect with a one-line config change.
Write YAML policies that cap what each agent can request. An agent asking for full GitHub write but your policy says read-only? Alter downgrades it automatically, logs the delta.
Alter issues tokens with a TTL you control — default 4 hours. When the TTL expires, the token is revoked automatically. No manual cleanup, no zombie credentials.
Every token mint, use, and revocation is logged with agent ID, run ID, task context, and timestamp. Export to Splunk, Datadog, or any SIEM via webhook.
