Many assume that giving Claude a permanent API token is enough to keep AI‑driven skills secure. In reality, static credentials linger in code repositories, CI pipelines, and developer workstations, providing a perpetual foothold for anyone who discovers them.
When a skill calls Claude, the request travels directly from the invoking service to the LLM endpoint. The service presents the stored token, Claude validates it, and the interaction proceeds without any visibility into who initiated the call or why. If the token is compromised, an attacker can generate unlimited prompts, exfiltrate proprietary data, or cause costly token‑based billing spikes.
Just-in-time access changes that model. Instead of a long‑lived secret, the system issues a short‑lived credential only at the moment a skill needs to run. The credential expires after the request finishes, limiting the window for abuse and ensuring that every invocation can be tied to a specific identity and intent.
Just-in-time access for Claude Skills
Implementing just-in-time access for Claude skills requires three pieces: an identity source that can issue short‑lived tokens, a network‑resident gateway that can enforce policies on the request, and a set of guardrails that record, mask, or pause the interaction as needed.
Setup – identity and provisioning
The first step is to define a non‑human identity that represents a Claude skill execution. OIDC providers such as Okta, Azure AD, or Google Workspace issue short‑lived JWTs that encode the caller’s group membership and purpose. The caller presents these tokens to the gateway, which validates the signature and extracts the claims. Because the token is short‑lived, a compromised token cannot be reused after its expiry.
The data path – where enforcement lives
hoop.dev sits on the network edge between the caller and the Claude endpoint. The gateway proxies all traffic to Claude, so the gateway becomes the only place where policy decisions can be applied. The gateway never forwards the caller’s original secret; instead, it presents a temporary credential that it fetches from a secure store.
Enforcement outcomes
hoop.dev verifies the caller’s identity, then grants the temporary credential to Claude only after verification succeeds. While the request is in flight, hoop.dev records the full request and response stream, providing a replayable audit log for investigations. If a response contains fields marked as sensitive, hoop.dev masks those values before they reach the caller, preventing accidental leakage of proprietary prompts or results. For high‑risk prompts, such as those that could trigger data extraction or costly token usage, hoop.dev can pause the request and route it to a human approver. hoop.dev logs the approver’s decision, and hoop.dev proceeds with the request only after explicit consent.
Because hoop.dev is the only component that can see and manipulate the traffic, every enforcement outcome, temporary credential issuance, session recording, inline masking, and just‑in‑time approval, depends on hoop.dev’s presence in the data path. Without the gateway, the identity verification step would still happen, but there would be no place where the request could be inspected, altered, or halted.
Why this matters for Claude skills
Claude skills often process confidential business logic, proprietary data, or user‑generated content. A single unguarded call can expose that data to downstream systems or external observers. By inserting hoop.dev, organizations gain visibility into each skill execution, enforce least‑privilege credentials, and ensure that any sensitive output is sanitized before it leaves the LLM.
Deploying the gateway is straightforward. The getting‑started guide walks you through a Docker‑Compose deployment, while the learn section provides deeper coverage of masking policies, approval workflows, and session replay. Once the gateway runs, you register the Claude endpoint as a connection, bind it to the short‑lived identity, and enable just‑in‑time access in the policy UI.
FAQ
- Can I still use existing Claude API keys? Yes, but hoop.dev stores them. Callers never see the key; hoop.dev injects it on their behalf for the duration of the request.
- What happens if a request is denied? hoop.dev returns a clear denial response that includes the reason (for example, missing approval). hoop.dev logs the denial alongside successful sessions for full auditability.
- Is the audit data tamper‑proof? hoop.dev records each session in an append‑only store that is separate from the caller’s environment. hoop.dev exports the logs for compliance reporting or forensic analysis.
