Problem / agitation / control

A model gateway can secure the request and still leave the agent over-privileged.

Enterprise risk moves beyond inference when an autonomous workload retrieves a SaaS token, calls a tool, changes a record, or exports regulated data.

Model route

Select provider, model, region, fallback, rate, and budget policy.

Workload identity

Bind the autonomous runtime to an owner, team, environment, and deployment.

Action authority

Evaluate the tool, operation, business resource, parameters, and runtime context.

Secretless execution

Inject the minimum credential at runtime without returning it to the agent.

Control capability matrix

Gateway features are only one layer of agent security.

Compare the documented LiteLLM product focus with the planned Agent Access Manager control-plane architecture.

Control domain	Enterprise requirement	LiteLLM	Agent Access Manager
Gateway	Multi-provider LLM routing and fallback Maintain provider resilience without changing application endpoints.	Native Multi-provider proxy routing, retry, and fallback are documented core capabilities.	Core control-plane design Policy-aware model routing and fallback are part of the planned gateway path.
Gateway	Virtual access keys, budgets, and rate policy Separate application access from provider credentials and constrain spend.	Native Virtual keys, teams, budgets, and rate limits are documented gateway features.	Core control-plane design Virtual access, model entitlement, budget, and rate policy share one identity context.
Identity	Cryptographic AI agent workload identity Verify the autonomous runtime, not only the API key used by its application.	Key and user context Gateway identities and access controls are documented; cryptographic agent workload identity is not the primary abstraction.	Core control-plane design Every agent resolves to a verifiable workload identity, owner, team, and environment.
Authorization	Runtime tool and action authorization Evaluate the exact resource and operation before an agent executes it.	External implementation LLM guardrails are documented, while downstream tool-action authorization typically lives outside the proxy.	Core control-plane design Action policy evaluates tool, operation, resource, parameters, and runtime context.
Credentials	Credential injection outside agent context Let an agent complete approved work without receiving the downstream secret.	Application responsibility Provider secrets are centralized, but downstream SaaS credential mediation is a separate implementation concern.	Core control-plane design Credentials are injected inside the controlled execution path and withheld from agent context.
Evidence	Identity-to-action audit evidence Connect delegation, policy, credential use, model traffic, tool action, and outcome.	Gateway-level telemetry Model request logs and spend context are available; downstream action outcomes require external correlation.	Core control-plane design The evidence model links workload identity through the final authorized action outcome.

Migration path / controlled evaluation

Evaluate the missing control layer without a blind rewrite.

Start from the routes, providers, and operational controls your platform team already runs. Then introduce agent identity, tool grants, and runtime credential policy at explicit boundaries.

Architecture FAQ

Agent Access Manager vs LiteLLM

Is Agent Access Manager a LiteLLM fork?+

No. Agent Access Manager is positioned as a separate enterprise control-plane architecture focused on agent identity, action authorization, and credential mediation in addition to LLM gateway controls.

Can LiteLLM and Agent Access Manager coexist?+

A phased architecture can retain an existing model proxy while introducing identity and action policy at the agent execution boundary. Final integration depends on deployment and API compatibility requirements.

What is the main architectural difference?+

LiteLLM's documented center of gravity is model access and proxy operations. Agent Access Manager is designed around the full path from workload identity through model routing to an authorized downstream action.
