Azure AI Gateway

Configure Azure API Management (APIM) as an AI Gateway for governing AI models, MCP tools, and agents.

To deploy APIM, use the azure-prepare skill. See APIM deployment guide.

When to Use This Skill

CategoryTriggers
Model Governance"semantic caching", "token limits", "load balance AI", "track token usage"
Tool Governance"rate limit MCP", "protect my tools", "configure my tool", "convert API to MCP"
Agent Governance"content safety", "jailbreak detection", "filter harmful content"
Configuration"add Azure OpenAI backend", "configure my model", "add AI Foundry model"
Testing"test AI gateway", "call OpenAI through gateway"

Get Gateway Details

# Get gateway URL
az apim show --name <apim-name> --resource-group <rg> --query "gatewayUrl" -o tsv

# List backends (AI models)
az apim backend list --service-name <apim-name> --resource-group <rg> \
  --query "[].{id:name, url:url}" -o table

# Get subscription key
az apim subscription keys list \
  --service-name <apim-name> --resource-group <rg> --subscription-id <sub-id>

Test AI Endpoint

GATEWAY_URL=$(az apim show --name <apim-name> --resource-group <rg> --query "gatewayUrl" -o tsv)

curl -X POST "${GATEWAY_URL}/openai/deployments/<deployment>/chat/completions?api-version=2024-02-01" \
  -H "Content-Type: application/json" \
  -H "Ocp-Apim-Subscription-Key: <key>" \
  -d '{"messages": [{"role": "user", "content": "Hello"}], "max_tokens": 100}'

Common Tasks

Add AI Backend

See references/patterns.md for full steps.

# Discover AI resources
az cognitiveservices account list --query "[?kind=='OpenAI']" -o table

# Create backend
az apim backend create --service-name <apim> --resource-group <rg> \
  --backend-id openai-backend --protocol http --url "https://<aoai>.openai.azure.com/openai"

# Grant access (managed identity)
az role assignment create --assignee <apim-principal-id> \
  --role "Cognitive Services User" --scope <aoai-resource-id>
Apply AI Governance Policy

Recommended policy order in <inbound>:

  1. Authentication - Managed identity to backend
  2. Semantic Cache Lookup - Check cache before calling AI
  3. Token Limits - Cost control
  4. Content Safety - Filter harmful content
  5. Backend Selection - Load balancing
  6. Metrics - Token usage tracking

See references/policies.md for complete example.

Troubleshooting

IssueSolution
Token limit 429Increase tokens-per-minute or add load balancing
No cache hitsLower score-threshold to 0.7
Content false positivesIncrease category thresholds (5-6)
Backend auth 401Grant APIM "Cognitive Services User" role

See references/troubleshooting.md for details.
