Audit whether every data operation is scoped to the caller's tenant, so a request in one tenant cannot read or write another's data. Covers a query or object lookup with the object identifier but no tenant predicate, a tenant taken from client-controlled input at the operation rather than the authenticated session, scoping applied on the list path but dropped on the detail, update, delete, or export path, a cache or storage key with no tenant segment, and a background job, report, or…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Auditing multi-tenant isolation: is every operation scoped to the caller's tenant When one system holds many tenants' data, isolation is an invariant that has to hold everywhere at once: every query, cache read, storage access, search, and background job is scoped to the tenant the request is authenticated as, and to no other. A single unscoped operation is not one bug but a whole class of cross-tenant access at that point. This is the systemic view, distinct from asking whether one object reference is owner-checked; here the question is whether the boundary is enforced by construction across the codebase. You audit it by finding the tenant value at each data operation and tracing it back: does it come from the authenticated session, or from something the client controls, and is there a mandatory scope that covers this path at all. The decisive false positive is a central, invisible enforcement, a global scope or a row-level policy, so establish that first. ## When to use - One deployment or database serves multiple tenants, organizations, or workspaces, separated by a scope rather than by isolation. …

How to install
mdr add unboundcompute/security-agent-skills/auditing-multi-tenant-isolation@sha256:2b9809990b030644The line at the top of this page pins the label git:20260821.57dfaf1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
