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
DISCORD_WEBHOOK_URLMATRIX_ACCESS_TOKENSLACK_WEBHOOK_URLTELEGRAM_BOT_TOKENWEBHOOK_ENDPOINT_URLWEBHOOK_SECRET_KEYWHATSAPP_ACCESS_TOKENConfiguration, not credentials: MATRIX_HOMESERVER_URL, MATRIX_ROOM_ID, OMNIBRIDGE_QUEUE_DB, WHATSAPP_API_VERSION, WHATSAPP_PHONE_NUMBER_ID
Where it talks to
no vendor host named in the codeAlso discord.com, discordapp.com, matrix.org, slack.com, telegram.org, facebook.com — not the publisher's domain; check what for before connecting.
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, and read the third-party hosts first. The code names discord.com, discordapp.com, matrix.org, slack.com, telegram.org, facebook.com as well as its own vendor. The guard injects DISCORD_WEBHOOK_URL, MATRIX_ACCESS_TOKEN, SLACK_WEBHOOK_URL, TELEGRAM_BOT_TOKEN, WEBHOOK_ENDPOINT_URL, WEBHOOK_SECRET_KEY, WHATSAPP_ACCESS_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

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 2026-11-13 and scored it 68/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Credential pass-through configuration; Discord webhook URL; Slack webhook URL. Summary: no network, touches nothing outside the project, writes no memory.
