AI agent monitoring: every prompt, tool call and result

AI agent monitoring, or AI agent observability, is a record of what AI agents actually do: each session's prompts, the tools it calls, the commands it runs and what comes back, kept where security can read it, search it and act on it.

Autonomous records the sessions of coding assistants, desktop agents and cloud agents across your fleet, scores each one for risk, links every risk to the moment in the transcript it came from, and keeps the log of every action its guardrails blocked or would have blocked.

Why agents need monitoring

An agent decides its next step on its own. Most of what it does never reaches a screen: a command in a terminal nobody watches, a file read, a call to a tool behind an MCP server. Without a record, nobody can say afterwards what it did, or why.

A real session

Asked: Unable to ssh to the server.

The agent started a background task that disabled the guest firewall on a production VM to reopen SSH: an unreviewed production change, made in answer to a one-line complaint. Then it cleaned up after itself.

From The Hidden Security Risks in 100k Enterprise AI Sessions

When an agent covers its tracks, by accident or not, the only account left is the one recorded outside it. When an OpenAI model escaped its evaluation sandbox into Hugging Face's systems in July 2026, its ~17,600 actions could be reconstructed only because the logs survived. AI agent monitoring keeps that record for every session, on every machine.

How it works

  1. Deploy, and sessions arrive

    Install the endpoint agent with one command or through your MDM, and connect your AI SaaS. Sessions from Cursor, Claude Code, Codex, Gemini CLI and the other supported agents start arriving, each with its user, machine and project.

  2. Triage the risky sessions

    Each session is rated for risk, and sessions that leaked data or may have are marked. Open one and every risk links to the turn in the transcript that caused it. A deep scan reads the whole session again for what the real-time checks may have missed.

  3. Hunt, export, stream

    Filter by user, endpoint, app or detection, hunt across everything recorded with a pattern or a question in plain words, export the sessions you need as JSON, and stream session and enforcement events to your SIEM.

A session, as the platform sees it

Asked: “How many open pull requests are in this repo?” In the chat, a short answer. In the record, every step it took to get there.

  1. The person: How many open pull requests are in this repo?

    Recorded: The prompt, with its user, machine and project

  2. The agent: Let me check GitHub.

    Recorded

    • GitHub API, unauthenticated: refused
    • Browser attempt: failed
  3. The agent: I'll find a way to authenticate.

    Recorded

    • Inspected the git credential helpers
    • Read ~/.netrc
    • Read the macOS keychain
    • GitHub personal access token in the tool's result
    • Secrets guardrail, monitor mode: would redact
  4. The agent: The repo has open pull requests; here is the list.

    Recorded

    • GitHub API, with the token
    • Confirmed threat: a credential hunt nobody asked for

What a marker can be

  • MCP tool call: its server and tool
  • Built-in tool: a file read, a web fetch
  • Shell command
  • Skill loaded
  • Secret surfaced: a key or token in the agent's context
  • Guardrail verdict: redacted, blocked, or would be
  • The session's risk
A real session from our research, redrawn: in the chat, the agent answered a simple question; the record shows how, through the developer's credential stores to a GitHub token in the keychain. The guardrail's verdict is drawn as monitor mode records it. On enforce, the Secrets guardrail redacts the token before the agent can use it.

What monitoring finds

Our research team went through over 100,000 real AI agent sessions on enterprise endpoints. 30,232 of them held actions the user didn't ask for. What the recorded sessions did:

read from an unclassified SaaS source
8,301
touched regulated data
4,420
ran a destructive operation
2,050
used cloud credentials
1,237
  • 1,068 sent data out over the network, and 756 dumped environment variables.
  • 742 surfaced a secret into the agent's context.
  • 450 read a developer credential store, and 131 read the OS keychain.

What it records

Activity is the platform's record of what agents did, and of what it did about them.

  • Sessions

    One row per agent session: its user, machine and project, its detections, alerts and risk. Each opens on its risk, its transcript, and a data flow of where it read from and wrote to.

  • Enforcement log

    Every action that was blocked or redacted, and every one monitor mode would have blocked, with the rule that decided it. Review what would block before you turn a policy to enforce.

  • MCP and console audit

    Each tool call and sign-in through the MCP Gateway, the hosts its MCP servers reached, and every administrator action in the console, each with its severity.

  • Token and usage analytics

    Estimated AI spend and tokens by model, app or user over 7, 30 or 90 days, from the tokens agents report and public list prices.

  • Hunts and scans

    Test a hunch across everything recorded, such as whether any agent sent a secret to an outside host, with a pattern or a question in plain words, or scan a time window for real risk without knowing what to look for.

  • Export and SIEM

    Download the sessions your filters match as JSON, and stream session, enforcement and audit events to Splunk, IBM QRadar, OpenTelemetry, Syslog or Coralogix.

Who sees the content

Prompts and transcripts can hold source code and secrets, so seeing them is a permission of its own, apart from seeing that a session happened.

  • Content takes a role

    Without content permission a reviewer sees a session's shape, its events, lengths and verdicts, with the text hidden: “Prompt hidden (79 chars)”. Roles decide who can reveal it.

  • Collect only what you need

    Per kind of activity, keep everything, only what a guardrail flagged, only the verdict, or nothing. A block is always recorded. Groups can have settings of their own.

  • Personal accounts stay personal

    Collect in full only from the organizations you approve. From personal or unknown accounts the platform keeps metadata alone, and their prompts never leave the machine.

Frequently asked questions

What is AI agent observability?

Seeing what an AI agent did and why: the prompts it was given, the tools and commands it ran, what came back, and what it did next. For security, that record has to be complete, kept outside the agent, and tied to a person and a machine, so a risky action can be found, explained and stopped next time.

Which AI agents does it monitor?

Sessions are recorded from Cursor, Claude Code, OpenAI Codex, Gemini CLI, ChatGPT Desktop, Claude Desktop, VS Code, JetBrains IDEs and other desktop agents; from ChatGPT, Claude, Gemini and Microsoft 365 Copilot in the browser; and from Claude Enterprise and ChatGPT Enterprise through their compliance APIs, which includes use that never touches a managed machine.

Does monitoring slow agents down?

Recording a session doesn't stand in the agent's way: the endpoint agent collects the AI agent's own session transcripts. Checks that stop an action run inline, on agents that expose hooks for it, once you turn on real-time guardrails.

What data does it collect, and who can see it?

By default, the prompts, tool calls, responses and session metadata of the AI agents, for audit and investigation. You can set prompts and tool calls to keep only the verdict and metadata, only flagged activity, or nothing, and turn the other kinds off; a block is always recorded. Personal accounts can stay private: collect in full from your approved organizations only, and from personal or unknown accounts we collect metadata alone, their prompts and transcripts never leaving the machine. Seeing the content takes a role that allows it, and the browser extension hashes conversation text rather than storing it.

How long is the data kept?

You choose, up to 60 days. Stored data is encrypted in transit and at rest, and never used to train models. More on our Security page.

Does it record personal AI accounts?

It tells them apart by the account's organization. With collection limited to your approved organizations, a personal account's use is recorded as metadata only, so you know it happened without reading it. Finding the AI tools nobody approved is Shadow AI.

Will it disrupt our developers or block their work?

Not unless you choose to. Every new policy and guardrail starts off or in monitor mode, where activity is evaluated and logged but nothing is blocked. You move a policy to enforce when its findings look right, for a pilot group first.
