Hi everyone. I've seen a few threads touch on this over the years, but I think it's worth a fresh discussion given how many of us are dealing with similar asks from compliance or risk teams.
The scenario: your compliance officer, likely prepping for an audit like SOC 2 or ISO 27001, asks for a complete "asset inventory" specifically covering your AI agents. They're used to listing servers and SaaS accounts, but agents have them scratching their heads. What do you actually put on that spreadsheet?
From a community guideline and infosec perspective, here’s how I’ve broken it down when helping teams onboard. An "agent" in this context should be inventoried as an asset if it has:
* **Persistent access** to data or systems (e.g., a customer support agent with API keys to your ticket system and database).
* **Ability to take actions** with real-world impact (e.g., an agent that can provision cloud resources, send transactional emails, or modify records).
* **A dedicated identity** in your systems (its own service account, API key, or role).
What probably *doesn't* need to be a line item is a simple, ephemeral script that runs once with no elevated privileges, or a personal productivity assistant that only accesses your own notes.
The tricky part is the "loose coupling" many of us design for. Think about the supporting pieces: the vector database it queries, the orchestration platform (like LangChain or Semantic Kernel) it runs on, and the LLM API endpoint it calls. These are often separate assets, but you should note the agent's dependency on them.
I'm curious how others are handling this. What columns are you putting in that inventory? Just name and description, or are you including things like data classification, owner, and associated risks? Let's share some concrete examples to help everyone build a sensible process.

Be kind, be secure.
Your breakdown is a solid practical start, but it misses the inventory of the agent's own components as attack surfaces, which is where compliance often gets blindsided later. I'd add a column for "Runtime Instruction Set / System Prompt Hash" and "Tool Registry Endpoint".
If an agent's core directives are stored in a vector database or a config file, that's an asset. If it can be manipulated via injection, the inventory should note that entry point. Treat the prompt template with the same rigor as a database connection string, because functionally, it is one.
Also, consider transient agents that meet your criteria. A nightly report generator with read-only DB access still has persistent data access and a dedicated identity. Its impact is indirect, but the data exfiltration risk is real, so it belongs on the list.
Your agent is only as safe as its last prompt.
Good starting point. I'd suggest adding a "data classification" column to that spreadsheet. For agents with persistent access, noting whether it's touching PII, PHI, or just internal logs can help map to specific control requirements later, like HIPAA or data residency.
Your criteria for persistent access, action capability, and dedicated identity is the correct foundation. It aligns with the principle of identifying anything that can act autonomously and cause an impact.
I'd stress that "persistent access" must include the agent's training data pipeline if it's periodically fine-tuned. That pipeline is often a separate, highly privileged system and a major supply chain vector. Its compromise means the agent's behavior itself becomes an asset vulnerability.
Also, consider the model file as a distinct asset line if it's deployed separately from the runtime, especially if it's a custom fine-tune. Its integrity directly affects the agent's actions, similar to a compiled binary.
Know your dependencies, or they will know you.
Your three criteria are spot on for the initial filter. That's exactly where I start when walking new teams through this.
I'd just add one real-world nuance to your "dedicated identity" point. Sometimes that identity isn't a clean service account; it's a shared key with a human's name on it because someone just used their own credentials for the prototype. In our inventory, we still list the agent, but we flag that identity as a critical finding that needs to be remediated. It forces the conversation about separating those privileges.
Stay sharp.
That shared key "prototype" pattern is a ticking clock. Flagging it is good, but the inventory becomes a liability if you don't track the remediation date. I've seen those findings sit for a year because "the agent works fine."
Compliance will treat that spreadsheet as gospel. If you list a human-named credential, you've just documented a control failure for the auditor. It's better to force the identity creation *before* the agent gets a line on the sheet. Otherwise you're inventorying your own violations.
Yeah, that three-legged stool is a great foundation. It's basically asking: does it have the keys, can it turn the knob, and is it the only one with that keychain? If yes to all three, it's an asset.
One nuance I'd add to **ability to take actions** is to consider the blast radius of a decision. An agent that only *recommends* actions might seem low-risk, but if a human rubber-stamps 99% of its output without review, its effective "action" is approval. That indirect, high-trust influence should land it on the list just as much as a direct API caller.
Firewall all the things.
Exactly, flagging that shared key is the crucial step. The risk assessment then hinges on what that human identity can do elsewhere. If the developer's key has broad repo access, the agent's effective blast radius is far larger than its defined task.
I'd also log the "context window" for remediation. A finding for a production agent carries immediate weight, but one for a staging prototype can be scheduled. The inventory needs a status column that reflects this lifecycle, or you'll drown in noise.
