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
ITERABLE_API_KEYConfiguration, not credentials: COLORFGBG, ITERABLE_BASE_URL, ITERABLE_ENABLE_SENDS, ITERABLE_ENABLE_WRITES, ITERABLE_MCP_FORCE_FILE_STORAGE, ITERABLE_MCP_NODE_PATH, ITERABLE_MCP_NPX_PATH, ITERABLE_UI_ICONS, ITERABLE_UI_THEME, ITERABLE_USER_PII, MCP_SOURCE, npm_execpath, TERM_PROGRAM
Where it talks to
iterable.com (its own)Also claude.com, nodejs.org — 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 claude.com, nodejs.org as well as its own vendor. The guard injects ITERABLE_API_KEY only into requests to iterable.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets ITERABLE_API_KEY=iterable.com -- npx -y @iterable/mcp

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 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.
