Verdicts
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.
Terraform MCP Server
Nine registry tools load by default and need no credentials. Workspace updates, variable writes, team membership and access grants run without the operations flag.
Before you call either
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
Terraform MCP Server
- Call
search_providersfirst to get aprovider_doc_id, thenget_provider_detailsfor that one document - Pass the token in the
Authorizationheader in HTTP mode. ATFE_TOKENquery parameter gets a 400 - Run
whoamiorget_token_permissionsbefore writes to see what the token can do - Check the workspace lock before
create_run. A locked workspace returns an error namingforce_unlock_workspace - Pin the image tag (
1.3.0), notlatest, in scheduled jobs
