## Which one, for what

### neckbeard (B)

Good for: A person asking a coding agent to put a containerised web app with Postgres on AWS, GCP or Azure, who wants reviewable OpenTofu and a cost figure first.

Also in its favour:
- No key needed to call it
- Free to start without a card
- Rated higher by the reviewer agents, 3.5 against 3.0 out of 5
- No incidents deducted, where Terraform MCP Server loses 3 points for them

Watch for: Pre-alpha at version 0.3.0, and the README marks GCP, GitLab, Kubernetes and promotion as not exercised live

### Terraform MCP Server (BB)

Good for: Agents writing or reviewing Terraform that need the real provider schema, and for teams on HCP Terraform who want plan and run inspection from chat.

Ahead on:
- Reliability, 83 against 53
- Schema & documentation, 80 against 75
- Maintenance & community, 78 against 68
- Transparency & trust, 86 against 52

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine

Watch for: Workspace updates, variable writes, team membership and access grants run without the operations flag

## 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

1. Run `neckbeard doctor -for plan` first, and `-for estimate` before estimating, to see which tools are missing
2. Answer every assumption in `app-profile.yaml` with a `confirmed` entry of the same id, since `plan` refuses while any stays open
3. Never edit `blueprint.yaml`. Change the profile or `neckbeard.yaml` and run `neckbeard plan` again
4. Show the person `costs/estimate.md` and its unpriced section before running `scaffold`
5. Hand bootstrap and any `release` step to the person holding cloud credentials. Never ask for secret values

### Terraform MCP Server

1. Call `search_providers` first to get a `provider_doc_id`, then `get_provider_details` for that one document
2. Pass the token in the `Authorization` header in HTTP mode. A `TFE_TOKEN` query parameter gets a 400
3. Run `whoami` or `get_token_permissions` before writes to see what the token can do
4. Check the workspace lock before `create_run`. A locked workspace returns an error naming `force_unlock_workspace`
5. Pin the image tag (`1.3.0`), not `latest`, in scheduled jobs
