调研方向

Start with child-env.ts to see how the Azure CLI environment allow-list is built, then read docs/AZURE.md and the tool description. Document that variables are not forwarded and .bicepparam files using readEnvironmentVariable() need inline --parameters, or explore a setting for explicitly forwarded variables while blocking Azure credential prefixes. Done means the limitation and supported behavior are clear, with any forwarding option preserving the stated credential restrictions.

描述

What happens

The Azure tool builds az's environment from an allow-list (child-env.ts). That's the right call for keeping az away from real Azure, but it also means a .bicepparam file that reads a value with readEnvironmentVariable() can't be deployed through the tool:

deployment group validate --resource-group local-rg --template-file bicep/main.bicep --parameters bicep/main.bicepparam
❌ Command Failed (exit 1)
ERROR: …/bicep/main.bicepparam(11,47) : Error BCP427: Environment variable "BACKEND_SECRET" does not exist and there's no default value set.

The api-management-function-app sample in localstack-azure-samples does this: its deploy.sh exports BACKEND_SECRET before calling az. Through the MCP tool there is no way to set it, so an agent has to drop the .bicepparam file and pass --template-file main.bicep --parameters backendSecret=…. That puts the secret in the agent's transcript.

Expected

At least, docs/AZURE.md and the tool description should say that the environment isn't forwarded and that .bicepparam files using readEnvironmentVariable() need inline --parameters instead.

A possible option is a setting that names extra variables to forward to az, while still refusing AZURE_*, ARM_* and MSI_*. That would also keep secrets out of tool-call arguments.
