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.
neckbeard
The agent maps an app onto human-maintained OpenTofu modules and a deterministic CLI renders them, so it writes no infrastructure by hand, and the cost table comes before any file is scaffolded. The project is pre-alpha at version 0.3.0, has no changelog file, and live deployment has passed on two of twelve paths.
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
neckbeard
- Run
neckbeard doctor -for planfirst, and-for estimatebefore estimating, to see which tools are missing - Answer every assumption in
app-profile.yamlwith aconfirmedentry of the same id, sinceplanrefuses while any stays open - Never edit
blueprint.yaml. Change the profile orneckbeard.yamland runneckbeard planagain - Show the person
costs/estimate.mdand its unpriced section before runningscaffold - Hand bootstrap and any
releasestep to the person holding cloud credentials. Never ask for secret values
