Intent-based runtime authorization

# WorkOS Airlock review

What WorkOS Airlock is, where it is strong, and where it falls short for securing AI agents and their tool calls. Every claim is drawn from WorkOS Airlock's own public material, listed in Sources.

Last updated: September 2026

## What WorkOS Airlock is

WorkOS Airlock is WorkOS's intent-based access control product for AI agents: it evaluates each tool call at runtime from the agent's stated intent and returns approve, deny, escalate-to-human or request-more-info, with agent identity and delegated authority, credential brokering, capability declarations, approval workflows through Slack, content rules (secrets, credentials, financial data, phone numbers), a prompt-injection rule and cross-system exfiltration checks, delivered as a hosted service that works over MCP, behind any MCP gateway and inside coding harnesses like Claude Code, Codex and OpenCode.

## Where WorkOS Airlock is strong

- Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact.
- Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry.
- Provable per-call audit. A receipt for every call: agent, tool, policy version, result.
- SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access.
- Tool-level policy. Read and write tiers, per-tool rules and human-in-the-loop approvals.

## Where WorkOS Airlock falls short

Measured against a runtime agent data firewall. These are the gaps that matter if your priority is stopping data loss at the point of the tool call.

- SealGate runs a device-level agent that discovers shadow MCP servers on the endpoint and keeps local stdio servers on the device through a tunnel; Airlock has no endpoint presence, it sits behind a gateway and brokers calls through WorkOS's cloud pipes.
- SealGate self-hosts fully in your own VPC, on-prem or air-gapped; Airlock is a hosted WorkOS service with no documented self-host or on-device deployment.
- SealGate scans all tool traffic for data loss with deep content DLP and streams a provable audit to your SIEM; Airlock enforces intent-based rules that can deny secrets, credentials or financial data and flags prompt injection, which is rule and intent evaluation rather than full-traffic DLP.
- Credit to Airlock: intent-based per-call verdicts, credential brokering, human-in-the-loop approvals through Slack and cross-system exfiltration checks are a real runtime layer, and if you are already standardized on WorkOS identity it slots in. SealGate is the alternative when you need on-device control, shadow-MCP discovery and self-hosting.

## WorkOS Airlock vs SealGate, feature by feature

SealGate leads with the rows at the top, its clearest points of difference, then the parity rows every enterprise gateway is expected to cover.

| Capability | SealGate | WorkOS Airlock |
| --- | --- | --- |
| How local stdio MCP servers are handled. Whether your local MCP server stays on the device or is shipped elsewhere. | Tunnel in place (Yes) | Behind gateway (No) |
| Local stdio servers stay on-device. The server keeps running on the machine, with no host-and-lift and no HTTP re-expose. | ✓ Yes | ✕ No |
| Device-level management. An endpoint agent that discovers and governs MCP activity on the device itself. | ✓ Yes | ✕ No |
| Interface coverage. Whether the gateway governs only the MCP protocol, or the agent CLI and LLM API too. | MCP + CLI (Yes) | MCP + harnesses (Partial) |
| Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact. | ✓ Yes | ✓ Yes |
| DLP, PII and secrets scanning. Inspects tool inputs and outputs for sensitive data at runtime. | ✓ Yes | ~ Partial |
| Prompt injection and tool-poisoning defense. Detects and stops injection, tool poisoning and rug-pull attacks. | ✓ Yes | ~ Partial |
| Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry. | ✓ Yes | ✓ Yes |
| Shadow MCP discovery. Finds unauthorized MCP servers before they are used. | ✓ Yes | ✕ No |
| Provable per-call audit. A receipt for every call: agent, tool, policy version, result. | ✓ Yes | ✓ Yes |
| SIEM integration and export. Streams audit events to Splunk, Sentinel and other SIEMs. | ✓ Yes | ~ Partial |
| SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access. | ✓ Yes | ✓ Yes |
| Tool-level policy. Read and write tiers, per-tool rules and human-in-the-loop approvals. | ✓ Yes | ✓ Yes |
| Self-host, on-prem or VPC. Run it in your own environment for data residency. | ✓ Yes | ✕ No |
| Compliance mapping. Evidence mapped to SOC 2, NIST AI RMF and the EU AI Act. | ~ Partial | ~ Partial |
| Low latency overhead. Minimal added latency on the tool-call path. | ✓ Yes | – Not publicly verified |
| Open source core. An open, inspectable core rather than a closed proxy. | ✕ No | ✕ No |

Bottom line: WorkOS Airlock and SealGate are both runtime firewalls that block agent tool calls inline; SealGate adds a device-level agent with shadow-MCP discovery, keeps local stdio servers on the device, self-hosts in your environment, and scans all tool traffic for data loss, where Airlock evaluates intent and content rules from WorkOS's cloud behind the gateway.

## Frequently asked questions

Is WorkOS Airlock an MCP gateway? Not exactly. Airlock is WorkOS's intent-based authorization layer that works over MCP and behind any MCP gateway: it evaluates each tool call at runtime and returns approve, deny, escalate or request-more-info. It governs the decision on a call rather than proxying local stdio servers itself. SealGate is the gateway and firewall on the device that both routes the call and inspects its contents, so the two operate at different points on the path.

How is Airlock different from WorkOS's Auth for MCP? Auth for MCP is the OAuth authorization server that establishes who an agent is and which tools it may reach. Airlock is the runtime layer on top that judges each specific call from its intent and content, returning a per-call verdict and brokering the credential. WorkOS's identity platform is compared with SealGate on the WorkOS page; this page compares the Airlock runtime product.

What is WorkOS Airlock? WorkOS Airlock is WorkOS's intent-based access control product for AI agents: it evaluates each tool call at runtime from the agent's stated intent and returns approve, deny, escalate-to-human or request-more-info, with agent identity and delegated authority, credential brokering, capability declarations, approval workflows through Slack, content rules (secrets, credentials, financial data, phone numbers), a prompt-injection rule and cross-system exfiltration checks, delivered as a hosted service that works over MCP, behind any MCP gateway and inside coding harnesses like Claude Code, Codex and OpenCode.

What are the main limitations of WorkOS Airlock? The clearest gap for teams focused on runtime data security: SealGate runs a device-level agent that discovers shadow MCP servers on the endpoint and keeps local stdio servers on the device through a tunnel; Airlock has no endpoint presence, it sits behind a gateway and brokers calls through WorkOS's cloud pipes. Weigh this against your own priorities before deciding.

Is WorkOS Airlock worth it? It depends on the axis you care about. WorkOS Airlock and SealGate are both runtime firewalls that block agent tool calls inline; SealGate adds a device-level agent with shadow-MCP discovery, keeps local stdio servers on the device, self-hosts in your environment, and scans all tool traffic for data loss, where Airlock evaluates intent and content rules from WorkOS's cloud behind the gateway. Compare the two on the capabilities that matter to you.
