Front LLM calls behind a gateway: model routing, fallbacks, semantic caching, rate limits, key vaulting, cost controls, and unified APIs. Covers LiteLLM, Portkey, Azure AI Gateway / APIM, OpenRouter, AWS Bedrock proxy, and self-built gateways. Includes routing policies (cost/latency/capability/RBAC) and caching (exact + semantic).
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
# LLM Gateway and Routing > **Purpose**: Stop calling LLM provider SDKs directly from app code. Put a gateway in front so you can swap models, cap cost, and survive provider outages. --- ## When to Use This Skill - Multiple apps or teams calling LLMs in your org - Multiple providers in play (OpenAI + Anthropic + Azure + open-weights) - Need centralized cost, rate-limit, audit, and key management - Want semantic caching to cut spend - Need provider failover for SLO --- ## What a Gateway Buys You | Capability | Why | |------------|-----| | Unified API (OpenAI-compatible) | One client SDK, many backends | | Routing policy | Cheapest / fastest / most capable per task | | Failover | Provider outage does not page on-call | | Caching | Exact + semantic; 20-60% cost cut typical | | Rate limits & quotas | Per team, per tenant, per key | | Key vaulting | App never sees provider keys | | Cost attribution | Tag spans by team/tenant/feature | | PII / safety hooks | Central guardrails | | Audit log | Compliance, incident response | --- ## Gateway Options | Gateway | Notes | |---------|-------| | **LiteLLM** (OSS + cloud) | 100+ providers, OpenAI-compatible, easy self-host | …

How to install
mdr add jnpiyush/agentx/llm-gateway-and-routing@sha256:1365f78bfb1c977aThe line at the top of this page pins the label v1.0.0, 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.
