Use an API gateway for cross-cutting edge concerns without letting it absorb business logic, including the BFF variant. Use when fronting services with a gateway or untangling a bloated one.
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
# API gateway pattern A gateway is the single front door to many services, handling the concerns every client needs and no service should reimplement: routing, auth, rate limiting, TLS. Its failure mode is scope creep: the moment business logic leaks in, the gateway becomes a monolith every team must coordinate through. ## Method 1. **Put edge cross-cutting concerns in the gateway.** TLS termination, authentication (verify the token, pass identity downstream: see authn-design, jwt-handling), rate limiting (see rate-limiting), request routing, and common observability (see distributed-tracing's entry span): the things every request needs and every service would otherwise duplicate inconsistently. 2. **Keep business logic out, ruthlessly.** The gateway routes and enforces; it does not know that an order over $1000 needs approval: that is a service's job. Business rules in the gateway recreate the distributed monolith's coupling at the edge, where every team's change now waits on the gateway team (see microservices-boundaries' coupling warning). 3. **Use the BFF variant for divergent clients.** When a …

How to install
mdr add amey-thakur/ai-skills/api-gateway-pattern@sha256:061661b8ffc71db2The line at the top of this page pins the label git:20260720.67d6135, 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.
