Verdicts
AWS MCP Servers
Knowledge server is hosted, free, GA and needs no account or key. No published rate-limit numbers, retry guidance or status component for the Knowledge server.
Azure MCP Server
Entra ID through DefaultAzureCredential, so access follows RBAC and no secret sits in the MCP config. npm latest installs a 3.0.0 beta, and betas rename and remove tools without a notice period.
Before you call either
AWS MCP Servers
- Use
https://knowledge-mcp.global.api.awsfor docs and regional availability. It's rate-limited with no published numbers, so cache results - Call
get_regional_availabilitybefore proposing a service or CloudFormation resource in a region - Run the AWS API server with
READ_OPERATIONS_ONLY=truefor inspection, andREQUIRE_MUTATION_CONSENT=truewhen writes are allowed - Use a scoped IAM role, not an admin profile. IAM is the boundary the servers rely on
- Pin package versions. Releases land several times a month and can rename or remove tools
Azure MCP Server
- Start with
--namespace <one or two> --read-onlyfor inspection and widen only when a task needs a write - Pin a version instead of
@latest, which is a prerelease - Use
resiliency_*, notresilience_*. The prefix changed on 22 September 2026 - Resolve the subscription and resource group once and pass them on every call
- Auth failures mean the credential chain found nothing. Run
az loginor set the service-principal variables
