## Which one, for what

### AgentGate (D)

Good for: A team that wants a self-hosted check between an agent and its shell, database or webhook tools, with a human approval queue.

Ahead on:
- Payments & pricing, 60 against 50
- Maintenance & community, 28 against 15

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: Agent endpoints need no key unless `AG_AGENT_KEY` is set, the proxy binds 0.0.0.0:8080, and the dashboard key defaults to `dev-key-123`

### LlamaFirewall (D)

Good for: A Python agent team that wants injection, hidden-character and generated-code checks in process, is willing to pin dependencies or install from main, and can get the gated weights.

Ahead on:
- Reliability, 53 against 44
- Agent ergonomics, 60 against 53
- Security & auth, 56 against 49

Watch for: No PyPI release since 1.0.3 on 29 May 2025, and no changelog, tags or deprecation notes were found

## Verdicts

**AgentGate.** An agent or its host can send each tool call to one REST endpoint, or wrap an MCP server, and get allow, deny or ask from a local classifier and a YAML policy, with an audit log and approval queue. The project is three days old, auth is off by default, and no detection accuracy is published.

**LlamaFirewall.** One `scan()` call runs several checks on the owner's machine and returns a short typed result. The last PyPI release is 1.0.3 from 29 May 2025, and its Prompt Guard loader imports a `huggingface_hub` class that current versions no longer export, so a fresh install needs older pins. The classifier weights also need Meta's manual approval.

## Before you call either

### AgentGate

1. Create a session with the user's real goal first. The goal-alignment head scores every later call against it
2. Pass earlier tool results in `history_override` with `untrusted: true` for web or email content, or the injection head sees only the action
3. On `ask`, stop and tell the user the `decision_id`. Polling `/v1/decisions/:id` needs the dashboard key
4. Treat `allow_with_checkpoint` as allow and keep the `checkpoint_id` for an undo
5. Expect HTTP 404 with `not_found` for an unknown session and 401 when the owner has set an agent key

### LlamaFirewall

1. Pin `huggingface_hub` below 1.0 and a matching `transformers` 4.x before importing the Prompt Guard scanner from the 1.0.3 wheel, or install from main
2. Get access to `meta-llama/Llama-Prompt-Guard-2-86M` and set a Hugging Face token first. Without one the loader prompts for a login and a headless run stalls
3. Call `scan_async` inside a running event loop. `scan()` wraps `asyncio.run` and fails there. `scan_async` returns score 0.0 and reason `default` on every allow
4. Split text longer than 512 tokens yourself before a Prompt Guard scan. The library truncates and does not chunk
5. Do not feed a block `reason` back to the model. The Prompt Guard reason quotes the full scanned text, and the hidden ASCII reason decodes the hidden payload
