Credential broker for AI agents · Runtime control

Give agents approved access. Keep raw keys out of context.

Q: What is a credential broker for AI agents?

A credential broker mediates access between an agent and a service. It checks a request against policy and applies approved credentials on the agent’s behalf. Outloop calls its implementation an agent access router.

Q: Does the agent receive the raw credential?

In Outloop’s brokered API flow, the agent requests an approved action. The broker applies the credential host-side and returns a redacted result rather than the raw credential.

Q: How is this different from a secrets vault?

A vault manages secret storage and retrieval. A broker governs use of a credential for a particular request. They can be complementary; brokering does not remove the need for secure storage.

Q: How is this different from MCP authentication?

MCP authentication governs access to an MCP server. Downstream credential brokering governs how a request uses the provider’s credentials. The appropriate combination depends on your architecture and configured policies.

Q: Does Outloop issue short-lived credentials for every provider?

No. Outloop can apply existing credentials host-side; it does not universally mint short-lived credentials or implement provider-side token exchange.

Q: Can an agency credential serve more than one client workspace?

For supported services, workspace resource bindings can constrain shared access to an approved account, folder or property. Configure and verify the relevant provider binding; coverage is provider-specific.

Outloop checks the client workspace and requested action, uses the credential host-side and returns a redacted result. Your worker gets the capability it needs to do the job.

The right credential is only half the decision.

An agency credential may reach several client accounts. The workspace must also identify which account this particular job may use.

Supported resource bindings constrain access to the approved client account, property or folder before the provider call.

Know the boundary before you build.

Provider support variesResource bindings and available actions depend on the service and configured workspace policy.
Credentials still need secure storageBrokering governs use. It does not eliminate credential ownership, provider setup or rotation responsibilities.
Approval still mattersAuthorized access does not guarantee a correct result. Meaningful writes and client communication follow your approval process.

Vaults, MCP and short-lived credentials

A vault addresses storage; MCP provides a tool protocol and authentication model; a credential broker mediates downstream use. These layers can work together. Outloop does not universally issue short-lived tokens or claim enterprise identity lifecycle management.

Built by an agency operator

I'm Adam Argaman, founder of Outloop and CEO of a digital marketing agency.

After 15+ years across marketing, creative, data and systems—and 7+ years running client delivery—I built Outloop around the work agencies actually do.

The model needs a working environment: client Context, approved systems and clear human approval boundaries.
