On August 5, 2026, Anthropic announced Inference hooks — a beta feature for Claude Enterprise that inserts a real-time allow/deny checkpoint between a user’s prompt and the model. Before now, Anthropic’s documentation notes, native inline enforcement was limited to Claude Code’s client-side hooks; Inference hooks extends the same idea to every Claude Enterprise surface from one organization-level configuration.

What it actually does

Per Anthropic’s documentation, the flow is:

  1. A user submits a prompt on a governed surface (claude.ai, Cowork, or Claude Code — web, desktop, or CLI).
  2. Anthropic sends a signed HTTPS POST carrying the conversation transcript to the organization’s configured AI security server endpoint. Requests are signed per the Standard Webhooks specification once the organization generates its signing secret, so the receiving server can verify the request actually came from Anthropic.
  3. The organization’s server evaluates the content and returns a verdict — {"action": "allow"} or a deny with a reason — within a verdict timeout that defaults to 5 seconds (configurable).
  4. On allow, inference proceeds normally. On deny, the user sees a blocked message combining the server’s per-request deny_reason with a standing admin-configured message, and the denial is logged to the organization’s Activity Feed.

The same check runs a second time on the way out: when Claude calls a tool — including tools reached through MCP connectors, skills, or plugins — the tool’s response is checked before it’s returned to the model. The docs illustrate this with a Cowork example where a prompt and a Microsoft 365 tool result both get validated in the same conversation.

One detail worth flagging for anyone building an integration: Anthropic’s own announcement post describes the connection as a “signed WebSocket connection,” while the technical documentation is explicit that it’s a signed HTTPS POST webhook call, not a persistent WebSocket. The docs page is the one with the request/response schema and signature-verification details, so treat it as the authoritative description if the two disagree.

What it doesn’t do (yet)

The docs list real limits, not just a beta disclaimer:

  • Verdicts are binary. Allow or deny — there’s no rewrite-and-continue or redaction option.
  • Attachments are metadata-only. Your security server sees extracted text, not raw file or image bytes, so an image-only attachment (a screenshot of a document, say) isn’t inspected.
  • Only the prompt event exists at launch. Response-side enforcement (checking what the model generates, not just what goes in) is “planned as a later event,” per the docs — not live yet.
  • Not available everywhere. Inference hooks don’t cover Amazon Bedrock or Google Cloud deployments of Claude, voice mode, or Platform (API) organizations — Claude Enterprise only.
  • If your server doesn’t answer, the organization’s configured failure-handling setting decides whether the request is blocked or allowed through unchecked — this is an admin choice, not a fixed default.

Rollout controls and use cases

The docs describe staged-rollout tooling built in from the start: shadow mode (observe verdicts on live traffic without blocking anything), percentage-based rollouts (inspect a chosen fraction of requests), and role-based exclusions (exempt specific roles entirely) — so an organization doesn’t have to flip a hard switch on day one.

Anthropic frames four use cases in the announcement: data loss prevention (the “most common deployment,” per the docs) by forwarding transcripts to an existing DLP scanner; real-time transcript archival as a push alternative to polling Anthropic’s Compliance API (which we covered in detail back in May); prompt telemetry; and custom policy engines (model allowlists, project-scoped restrictions, working-hours rules). The announcement names four DLP vendors organizations can point the webhook at directly — Netskope, Palo Alto Networks, Proofpoint, and Zscaler — or a custom in-house server.

Andrew Grimmett, Vice President of Information Security at Bandwidth, is quoted in Anthropic’s announcement: “Inference hooks add a checkpoint to inspect what’s flowing to Claude in real time, before the model ever sees it. This lets us safely move faster on AI without giving up control.”

Availability

Inference hooks is live in beta today for Claude Enterprise organizations. Configuring it requires the organization:manage permission (held by Admin, Owner, and Primary owner roles, or any custom role granted it), per the docs. One hook configuration governs an entire organization’s claude.ai, Cowork, and Claude Code traffic — there’s no per-product setup.

Why this matters if you’re deploying Claude in a regulated org

Inference hooks is Anthropic’s answer to a specific gap: prior to this, the only inline, pre-inference enforcement point was Claude Code’s client-side hooks — everything else (the Compliance API) was after-the-fact audit, not a stop-the-request control. If your compliance team already runs a DLP program against other SaaS traffic and it speaks the Standard Webhooks protocol, pointing it at Claude Enterprise is now a configuration exercise instead of a custom build. The binary allow/deny model and prompt-only (not yet response-side) coverage are the real constraints to plan around before treating this as a complete inline-DLP solution.
