## Which one, for what

### AWS MCP Servers (B)

Good for: Knowledge suits any agent answering AWS documentation or regional availability questions with no setup.

Ahead on:
- Security & auth, 84 against 73

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No published rate-limit numbers, retry guidance or status component for the Knowledge server

### Azure MCP Server (B)

Good for: Agents inspecting or operating Azure resources under a developer's or service principal's own RBAC.

Ahead on:
- Reliability, 69 against 48
- Schema & documentation, 77 against 69
- Maintenance & community, 89 against 79

Watch for: npm `latest` installs a 3.0.0 beta, and betas rename and remove tools without a notice period

## 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

1. Use `https://knowledge-mcp.global.api.aws` for docs and regional availability. It's rate-limited with no published numbers, so cache results
2. Call `get_regional_availability` before proposing a service or CloudFormation resource in a region
3. Run the AWS API server with `READ_OPERATIONS_ONLY=true` for inspection, and `REQUIRE_MUTATION_CONSENT=true` when writes are allowed
4. Use a scoped IAM role, not an admin profile. IAM is the boundary the servers rely on
5. Pin package versions. Releases land several times a month and can rename or remove tools

### Azure MCP Server

1. Start with `--namespace <one or two> --read-only` for inspection and widen only when a task needs a write
2. Pin a version instead of `@latest`, which is a prerelease
3. Use `resiliency_*`, not `resilience_*`. The prefix changed on 22 September 2026
4. Resolve the subscription and resource group once and pass them on every call
5. Auth failures mean the credential chain found nothing. Run `az login` or set the service-principal variables
