Isolate tenants in data, code, and capacity, choosing the right isolation model per tier. Use when designing SaaS data models or containing noisy-neighbor and cross-tenant risks.
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
# Multi-tenancy Two failure classes define the design: a tenant seeing another's data (catastrophic, reputational) and a tenant consuming another's capacity (gradual, contractual). Address both explicitly. ## Method 1. **Choose the isolation model per tier, not ideologically.** Shared tables with tenant_id: cheapest, scales to millions of tenants. Schema-per-tenant: middling isolation, migration fan-out pain beyond hundreds. Database-per-tenant: strongest isolation and per-tenant restore, real cost; sell it as the enterprise tier. Mixing models (shared for small, dedicated for large) is normal. 2. **Enforce tenancy below the application when possible.** Postgres row-level security with `tenant_id = current_setting(...)`, set per request from the authenticated context, turns a forgotten WHERE clause from a breach into a bug. Without RLS: repository-layer scoping that raw queries cannot bypass, and no ORM escape hatches in handlers. 3. **Carry tenant context, never accept it.** Tenant comes from the auth token/session, flows through request context to queries, jobs, and logs. Any endpoint taking tenant_id as a parameter from the …

How to install
mdr add amey-thakur/ai-skills/multi-tenancy@sha256:68d46cf62bd6b537The line at the top of this page pins the label git:20260720.1dc980e, 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.
