Use for what-if questions when you are not about to act. Dry-run a proposed action against the organization policies (POST /v1/policies/test, one case, stored policies). This skips the PII scan and records nothing: no security event and no audit entry. There is no content field and no DLP scan. The result has no event id and no finalDecision. decide_action is the call that records a decision. Dry runs are limited to 60 requests per minute per key. test_policies covers up to 200 cases in one call.

Call this before a consequential action with any tool or connector: sending an email or message, exporting or sharing data, deleting data, writing to production or financial records, payments, or external API writes. ALLOW: proceed. REVIEW: hold the action, tell the user it waits for approval in Vulnify, and check again with get_decision. BLOCK: skip the action and explain the reasons. Records a decision for a proposed action (POST /v1/events). This writes a security event and an audit entry, counts toward the organization quota, and may open a human review. The finalDecision field is the authoritative result. decision is what was stored and does not change when a review is resolved. finalDecision stays REVIEW until a human approves, denies, or the review expires. This tool does not approve the review. A REVIEW or BLOCK finalDecision means the action was not allowed. Optional content is scanned in memory and is not stored. An idempotencyKey makes a retry return the same event.

Read a recorded decision (GET /v1/events/{id}), including a REVIEW. finalDecision is REVIEW while the review is pending, then ALLOW after approval or BLOCK after denial or expiry. decision itself does not change. The finalDecision field is the authoritative result. waitMs polls until finalDecision is ALLOW or BLOCK, or until the bounded wait elapses (30 seconds maximum). waitTimedOut is true when the wait ended and finalDecision is still REVIEW. This does not approve or deny the review.

List the organization policies as code (GET /v1/policies). Returns apiVersion vulnify.io/v1 and policies sorted by name. Read-only. Any non-revoked API key of the organization may call it. Limited to 60 requests per minute per key.

Evaluate up to 200 policy cases without recording an event (POST /v1/policies/test). When policies is omitted, the enabled stored policies are used. When policies is set, those proposed policies are evaluated instead and nothing is written. This skips the PII scan: cases have no content field. pass is null when a case omits expect. One call covers up to 200 cases. Limited to 60 requests per minute per key.

Diff policy creates, updates, and deletes without writing them (POST /v1/policies/apply). dryRun is forced to true and cannot be turned off. Nothing is stored and no audit entry is written. prune only marks missing policies for deletion in the plan. Requires an org-wide LIVE API key; a TEST key or an agent-bound key is refused with 403. This tool does not apply the plan.

Records a decision for a downstream MCP tool call (POST /v1/gateway/mcp). Vulnify maps the tool name to an action by substring and returns the same recorded decision as decide_action, including an id. This writes a security event and an audit entry. The tool arguments are not executed. The finalDecision field is the authoritative result. A REVIEW or BLOCK finalDecision means the downstream tool was not allowed. This server cannot approve the review. An idempotencyKey makes a retry return the same event.
