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: Caution 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
WIGOLO_LLM_API_KEYWIGOLO_SERVE_ALLOW_UNAUTHENTICATED or --allow-unauthenticatedConfiguration, not credentials: GITHUB_ACTIONS, TLS_BROWSER_PATTERN, WIGOLO_CONFIG_PATH, WIGOLO_DOCTOR_INPROC, WIGOLO_FIRECRAWL_COMPAT, WIGOLO_LLM_MODEL, WIGOLO_PLUGIN_AUTO_YES, WIGOLO_SEARCH, WIGOLO_SEARXNG_URL, WIGOLO_SERVE_ALLOW_LOCAL_TARGETS, WIGOLO_TUI_MODE, WIGOLO_TUI_REDUCED_MOTION, WIGOLO_WAIT_FOR_INDEX
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 WIGOLO_LLM_API_KEY, WIGOLO_SERVE_ALLOW_UNAUTHENTICATED 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.

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 2026-11-11 and scored it 76/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Privileged sudo command; Collapsed <details> block carrying instructions; Privileged sudo command. Summary: no network, touches nothing outside the project, writes no memory.
