AI Agent Incident Response: What to Inspect After an Agent Goes Wrong
AI agent incident response starts by inspecting identity, owner, endpoints, scopes, tool calls, payment records, public profiles, and replacement paths. After an agent goes wrong, teams should answer who the agent was, what it could access, what it did, which records are stale, and which identity callers should trust next.
For HeadlessDomains.com, the public identity record is the first inspection point. A .agent name can link responders to agent.json, SKILL.md, MCP metadata, proof links, directory profile, payment context, and policy pages before they decide whether to revoke, pause, replace, or retire the agent.
Incident Inspection Table
| Signal | Inspect | Evidence | Containment action |
|---|---|---|---|
| Unknown call | Source and target identity | .agent record, manifest, logs | Block caller or target endpoint |
| Suspicious tool use | MCP server, scopes, tool arguments | MCP metadata, gateway logs | Disable tool or revoke scope |
| Data exposure | Files, APIs, prompts, outputs | Audit logs and storage records | Freeze access and preserve evidence |
| Payment anomaly | Mandate, receipt, rail, authority | Payment logs and identity record | Revoke payment authority |
| Profile mismatch | Directory listing and manifest | Headless Profile Directory and agent.json | Update profile or mark compromised |
| Replacement | New identity and redirect path | Registry state and public record | Publish replacement identity |
Seven-Step Response Flow
1. Identify the Agent
Start with the canonical name, not only the endpoint. Resolve the .agent record, fetch the linked manifest, and compare the profile against internal registry data.
2. Freeze Risky Access
Pause high-risk tools, tokens, payment authority, delegated user access, and public endpoints while responders collect evidence. Avoid broad shutdown if a scoped pause contains the event.
3. Inspect Tool Calls
Review MCP calls, API requests, prompts, outputs, files, database actions, and authorization decisions. Microsoft and Okta both emphasize activity logs and governance controls for agent actions; those logs become the incident timeline.
4. Check Public Records
Compare the internal registry with agent.json, SKILL.md, Agent Cards, profile pages, endpoint docs, and directory listings. A stale public profile can send other agents to the wrong surface after containment begins.
5. Review Payments and Mandates
If the agent can move value or authorize checkout, inspect mandates, receipts, wallet links, payment rails, refunds, and support records. Revoke payment authority until the owner signs off.
6. Publish Status or Replacement
Mark the profile as paused, restricted, compromised, retired, or replaced. Link the replacement identity when another agent takes over the workflow.
7. Close With Review Updates
Update access review cadence, registry fields, offboarding playbooks, public records, and monitoring rules so the same failure mode is easier to catch next time.
Example Incident Record

HeadlessDomains.com gives incident response a stable inspection path. Even when an agent's tools, endpoints, or marketplace listings are changing, the .agent identity can show current status, replacement records, proof links, and public policy pages.

FAQ
What is AI agent incident response?
AI agent incident response is the process of identifying, containing, investigating, and updating records after an agent acts outside policy, exposes data, calls the wrong tool, or loses trusted status.
What should responders inspect first?
Start with identity: agent name, owner, manifest, profile page, endpoints, tool scopes, and logs. Then inspect tool calls, data access, payment authority, and replacement state.
How is this different from normal app incident response?
Agents can make dynamic tool choices, use delegated credentials, interact with peer agents, and expose public profiles. Response plans should include identity, manifests, prompts, tool calls, and public record updates.
When should a public profile change?
Change the profile when an agent is paused, restricted, compromised, retired, transferred, or replaced. Other agents may keep using old metadata unless the public record changes.
