## 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 68
- Maintenance & community, 79 against 68
- Transparency & trust, 72 against 52

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

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

### 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.

Ahead on:
- Reliability, 53 against 48
- Schema & documentation, 75 against 69

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 2.5 out of 5
- No incidents deducted, where AWS MCP Servers loses 5 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

## 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

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

### 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
