# AgentGuards setup — self-hosted
Unlike the hosted plugin, this variant has **no default backend** — it must be
told which appliance to use. Guide the user through both required variables.
## Steps
1. **Check for `AGENTGUARDS_URL`.** This is required here (the hosted plugin
defaults it; this one deliberately does not, so it can never silently talk
to the wrong instance). It should be the appliance's own address, reachable
from wherever Copilot CLI runs, over HTTPS.
2. **Check for `AGENTGUARDS_API_KEY`.** If missing, tell the user to generate
one on their appliance's own console at `<AGENTGUARDS_URL>/admin/ui/keys`,
then export it.
3. **If the appliance is still on its first-boot self-signed certificate**,
plain requests will fail with `CERTIFICATE_VERIFY_FAILED`. Two ways to fix,
both explained on the appliance's own `/admin/ui/docs#tls` page:
- `AGENTGUARDS_CA_BUNDLE=<path to the appliance's exported cert>` (pins it,
verification stays on — the better option)
- `AGENTGUARDS_TLS_NO_VERIFY=true` (evaluation on a private network only)
4. **Tell the user to add both variables to their shell profile**
(`~/.bashrc`, `~/.zshrc`, …), not just export them in the current terminal
— a one-off `export` is gone the moment the terminal closes or a new agent
session starts.
5. **Restart Copilot CLI** so it inherits them.
6. **Verify**: ask the user to try a prompt the guardrails block — asking to
be shown all the API keys works well. It should be refused with an
`[AgentGuards]` block panel. (Deliberately not spelling out a
prompt-injection payload here: plugin security scanners run YARA over skill
files and flag the literal string as an injection, which is how this file
once scored a critical finding for documenting an attack.) If
it isn't, the variables are likely not reaching the hook process — confirm
they're in the shell profile, not just the current shell.
