Microsoft Entra ID gives AI agents purpose-built, governed identities and controls access to protected resources. AgntID adds execution-time enforcement for each tool call.

Tool Execution
MCP tools
Run the agent as an application identity with its own credentials and permissions. This works for established workloads, but access is typically defined at the app, role, or resource level rather than around the task behind each tool call.
Act on behalf of the user with delegated access. The agent operates within the user's permissions and scopes, which may grant more access than the specific task requires.
Give the agent a dedicated identity with its own permissions, lifecycle, and access policies. Entra controls which resources the agent can access. AgntID adds task-level authorization by evaluating the task, tool, and arguments before each call runs.
OUR DIFFERENCE.
Microsoft Entra governs the agent's identity and which resources it can access. AgntID adds task-level authorization inside the execution path, evaluating each action in the context of the work being performed.
AgntID evaluates the task, tool, and arguments when the call is made. The decision is based on what the agent is trying to do in that specific action.
Access is scoped to the specific tool action and arguments required for that call, rather than inherited from broader permissions.
AgntID makes the authorization decision inside the tool-call path, before the action executes.
AgntID vs. The Alternatives
Each path below is real and solves something worth solving. Here's where it holds up, and where AgntID picks up the rest.
AGNTID VS. SERVICE PRINCIPALS
A service principal gives the agent an identity with permissions to apps, roles, and resources. It works well when access needs are known in advance. Those permissions are defined around the application identity, even when a specific task requires less. AgntID evaluates the task, tool, and arguments at runtime, then narrows access to the action being performed.
AGNTID IS BEST FOR TEAMS THAT NEED TO
SERVICE PRINCIPAL
Predefined app and resource permissions.
AGNTID
Access scoped to the current task and tool action.
DELEGATED USER ACCESS
Bounded by user permissions and scopes.
AGNTID
Access narrowed to this task, tool, and call.
AGNTID VS. DELEGATED USER ACCESS
Delegated access lets the agent act within the signed-in user's permissions and granted scopes. This works well when the agent is tied to a user session and acts on that user's behalf. The tradeoff is that the grant is still defined around what the user may access, which can exceed what one agent action requires. AgntID evaluates the task behind the call and narrows that delegated access to the specific tool action and arguments.

AGNTID VS. ENTRA AGENT IDENTITY
Entra gives the agent a dedicated identity with its own ownership, lifecycle, permissions, and access policies. It establishes the agent's identity and governs which resources it may access. Whereas AgntID adds task-level authorization inside each tool call. It evaluates the task, tool, and arguments before execution, then authorizes only what that action requires.

ENTRA AGENT IDENTITY
Identity, lifecycle, and resource access.
AGNTID
Determines what this exact action may do.
Microsoft Entra provides agent identity, governance, and access controls. AgntID adds task-level authorization inside the tool-call path. Together, they connect agent identity with runtime control.
| Capability | AgntID | Microsoft Entra ID |
|---|---|---|
Agent identity management Creates and manages a dedicated identity for each AI agent. | Partial | Yes |
Lifecycle, ownership, and access reviews Manages agent ownership, lifecycle, and ongoing access governance. | No | Yes |
Conditional Access for agent identities Applies Conditional Access policies to supported agent identities and agent user accounts. | No | Yes |
Task-aware authorization Evaluates the task, tool, and arguments, then narrows access to what the current action requires. | Yes | No |
Per-call runtime enforcement Evaluates each tool call inside the execution path before the action runs. | Yes | Partial |
Customer-hosted enforcement Runs runtime authorization inside the customer environment. | Yes | No |
Audit trail per tool call Records the authorization decision and context for each tool action | Yes | Partial |
No. Microsoft Entra ID remains the identity, governance, and access-control layer for your AI agents. AgntID adds per-call authorization to the identity and access controls Entra provides.
Microsoft Entra Conditional Access evaluates identity and policy signals to determine whether access should be granted. It does not evaluate the agent's task, tool, or arguments for each tool call. AgntID adds that decision inside the tool-call path.
Yes. Microsoft Entra Agent ID provides purpose-built AI agent identity, governance, and resource access. AgntID complements it by evaluating each tool call using the task, tool, resource, and parameters.
AgntID evaluates the task context, tool, resource, and parameters when the call is made. Each call is evaluated independently. Optional intent awareness can add another signal to the authorization decision.
Yes. AgntID can scope access to what the current task and action require rather than carrying broader permissions into every call.
AgntID runs inside your own infrastructure, in the tool-call path between AI agents and MCP servers.
