mcp-server-servicenow@0.9.3

CAUTION· not started

Publisher claims: "ServiceNow MCP server for Claude Code, GitHub Copilot, Codex and any MCP client: Table API, CMDB, schema, aggregates and update sets, plus four Agent Skills. Read-only mode, OAuth client credentials for headless use, audit log." 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: 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
SERVICENOW_AUTH_TYPESERVICENOW_PASSWORD or --client-secret / --mcp-oauth-client-id / --mcp-oauth-client-secret / --mcp-static-tokensConfiguration, not credentials: GITHUB_ACTIONS, GITHUB_REPOSITORY, GITHUB_RUN_ID, GITHUB_SERVER_URL, GITHUB_SHA, SERVICENOW_INSTANCE_URL, SERVICENOW_USERNAME
Where it talks to
no vendor host named in the codeAlso service-now.com, run.app, servicenow.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 service-now.com, run.app, servicenow.com as well as its own vendor. The guard injects SERVICENOW_AUTH_TYPE, SERVICENOW_PASSWORD only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx mcp-server-servicenow

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 2026-11-09 and scored it 72/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Credential pass-through configuration; HTML comment carrying imperative instructions to the agent. Summary: no network, touches nothing outside the project, writes no memory.
