opnsense-guard-mcp@0.1.1

VERIFIED· not started

Publisher claims: "Enables AI clients to inspect OPNsense 26.7+ firewall state and, with policy and a separate write-capable API user, plan, approve, apply, verify, and automatically revert firewall rule and alias changes under hash-chained auditing." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
OPNSENSE_GUARD_TOKENS_FILEOPNSENSE_WRITE_API_KEYOPNSENSE_WRITE_API_SECRETConfiguration, not credentials: MCP_TRANSPORT, OPNSENSE_GUARD_DATA_DIR, OPNSENSE_GUARD_ENV_FILE, OPNSENSE_GUARD_POLICY
Where it talks to
no vendor host named in the code
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard. It asks for OPNSENSE_GUARD_TOKENS_FILE, OPNSENSE_WRITE_API_KEY, OPNSENSE_WRITE_API_SECRET and talks to its vendor. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.

$vet-skills run --net declared -- <the server's command>

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-14 and scored it 80/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
