Why platforms need one identity layer for agents

A marketplace has many parties (sellers, buyers, partners, and the MCP services it exposes), and in the agent era each needs a consistent way to be verified and held accountable. LoginID gives platforms one identity layer that authenticates agents with Enhanced Web Bot Auth, binds them to accountable humans at NIST AAL2, scopes exactly what each agent may do per tenant with signed and revocable mandates, and secures the MCP and API surfaces agents call.

One identity layer for every party on your platform.

Multi-tenant agent identity

Issue and verify agent credentials across sellers, buyers, and partners, with every party bound to an accountable human at AAL2.

Fine-grained scopes and control

Decide exactly what each agent may do (read catalog, create orders, move money) with signed, revocable mandates.

Secure your MCP services

Authenticate the agents calling your MCP and API surfaces, so only verified, scoped actors reach your tools.

Marketplace-wide trust and audit

A consistent, phishing-resistant identity layer with non-repudiable proof of intent and a clear delegation chain across every transaction.

How a platform governs the agent era.

  1. 01

    Verify agents at the edge

    Authenticate every incoming agent with Enhanced Web Bot Auth before it touches your tenants or services.

  2. 02

    Bind, scope, and delegate

    Link each agent to a verified human and grant signed, revocable scopes per tenant and per action.

  3. 03

    Govern across the marketplace

    Enforce consistent trust, audit, and liability across every seller, buyer, and MCP service from one identity layer.

Frequently asked questions

How do you manage agent identity across a multi-tenant marketplace?
LoginID issues and verifies agent credentials across every seller, buyer, and partner from one identity layer, with each agent bound to an accountable human at AAL2. Scopes and mandates are enforced per tenant and per action.
How do you secure MCP services from unverified agents?
LoginID authenticates the agents calling your MCP and API surfaces so only verified, scoped actors reach your tools, blocking unknown or over-scoped agents at the edge before they touch your services.
What is an MCP service in this context?
An MCP (Model Context Protocol) service is a tool or API surface your platform exposes for AI agents to call. Because agents act autonomously, those surfaces need agent authentication and fine-grained, revocable authorization.
How does a platform enforce consistent trust and audit?
With one phishing-resistant identity layer providing non-repudiable proof of intent and a clear delegation chain, platforms enforce the same trust, audit, and liability standards across every seller, buyer, and transaction.
