AI Identity Propagation
You set up ai identity propagation by passing the user identity through every agent request. This setup links every database read or API call to the real person who asked. Most teams start by giving their AI app one shared service key. That shared key often holds broad read and write roles across many backend tools. When every prompt runs under one service role, your logs lose the human caller. A low-level user can ask the agent to pull records above their normal role. How ai identity propagat

You set up ai identity propagation by passing the user identity through every agent request. This setup links every database read or API call to the real person who asked. Most teams start by giving their AI app one shared service key. That shared key often holds broad read and write roles across many backend tools. When every prompt runs under one service role, your logs lose the human caller. A low-level user can ask the agent to pull records above their normal role.
How ai identity propagation works in practice
A user first logs in to the front-end app through your main identity provider. The identity provider checks the user and gives the app a signed token. That token holds the user ID, team group, and basic role claims. When the user sends a prompt, the app passes this token to the AI agent. The agent reads the prompt and decides which backend tool or database to call. Before the agent runs that call, it exchanges the user token for a downstream token. Standard token exchange flows let the agent request a new token for the target service. This new token keeps the original user identity and adds the agent identity as the actor. The target database or API then checks both identities before it runs the request. If the human user lacks the right role, the backend rejects the agent call.
Where native token flows fall short at runtime
Passing identity tokens solves the first step of knowing who logged in. It stops an agent from using one giant admin key for every single user. It also records the human caller inside your basic login logs. Still, native token flows only check roles when the session starts. They do not inspect what individual queries or commands do while in flight. A user with valid read roles can still prompt an agent to dump an entire table. Native identity tokens cannot rewrite sensitive fields like emails, phone numbers, or card numbers in results. If a prompt triggers a bad delete statement, the database role alone will not pause it. Teams also struggle when legacy databases do not accept modern identity tokens at all. In those cases, engineers fall back to shared database passwords and lose user context again. You need a way to link user identity to live query rules and field masking.
Steps to plan your agent identity flow
Start by mapping every tool and database your AI agent can reach today. Check which of those backend systems accept user tokens from your identity provider. Remove shared admin keys from agent worker nodes wherever user roles can work instead. Set up token exchange rules so agents only get short scopes for one task. Keep user roles narrow so an agent cannot read tables outside the team scope. Test what happens when a user asks the agent for data outside their group. Make sure your audit logs record both the human user and the agent name. Review the data returned by queries to see if raw card numbers or emails appear.

Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
Why is a shared service account risky for AI agents?
A shared key gives every user the same high level of database permissions. Audit logs only show the bot name, so you cannot trace who asked for data.
How does token exchange help with agent calls?
Token exchange trades the user login token for a narrow backend token. It keeps the original user ID attached while limiting what the agent can do next.
What happens when a database does not support identity tokens?
The app usually falls back to a static database user and password. Teams must then track the human user ID in a separate layer before queries run.
