An offboarded contractor’s CI job still holds a hard‑coded API key that talks directly to Cursor’s backend. The key was never rotated, and the job now runs on a shared runner that any developer can trigger. When the runner executes a query, the request bypasses any review, leaves no trace, and can exfiltrate sensitive code snippets. This is a classic machine identity problem: a credential that represents a non‑human actor, but that credential is treated like a static secret.
Why machine identity alone is insufficient
In most organizations the first line of defense is an identity provider. Engineers, service accounts, and CI pipelines receive OIDC or SAML tokens that prove who they are. That setup is essential – it decides who the request is and whether it may start. However, the identity check happens before the request reaches Cursor, and it does not inspect what the request actually does. The connection proceeds directly to the target service, carrying the credential unchanged. No audit log captures the exact query, no inline mask protects confidential fields, and no workflow can stop a dangerous command before it runs. The result is a blind spot where a compromised machine identity can cause data loss or lateral movement without any evidence.
What a secure data‑path gateway must provide
To close the gap, the enforcement point must sit on the data path itself. The gateway should be the only place where traffic to Cursor can be inspected, altered, or approved. It must be able to:
- Record each session so that auditors can replay exactly what a machine did.
- Mask or redact sensitive fields in responses, preventing secrets from leaking to logs.
- Require just‑in‑time approval for high‑risk commands before they reach the backend.
- Block commands that match a deny list, protecting the system from accidental or malicious misuse.
All of these capabilities rely on the gateway being the boundary between the identity provider and the Cursor service. Without that boundary, the machine identity remains a static credential with no real guardrails.
hoop.dev as the enforceable gateway
hoop.dev fulfills the data‑path requirement. It sits between the requestor – whether a CI job, an AI‑assisted tool, or a service account – and the Cursor backend. Because hoop.dev proxies the wire‑level protocol, it can inspect every query before it reaches the target.
When a request arrives, hoop.dev validates the OIDC token, extracts the machine identity, and then applies policy checks. If the query matches a rule that requires human approval, hoop.dev pauses the request and routes it to an approver. Once approved, the request is forwarded; if denied, hoop.dev blocks it entirely.
