mendapi@0.5.6

CAUTION· startup only

Publisher claims: "Detect API breaking changes, scan your codebase for impact, and draft the fix. Runs locally." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Startup only; authenticated tool behavior not tested.
Tested
server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
Not tested
the tool list (the server exited before answering) · what the tools do when called with real credentials

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
MENDAPI_LLM_API_KEYConfiguration, not credentials: MENDAPI_DB, MENDAPI_LLM_BASE_URL, MENDAPI_LLM_MODEL, MENDAPI_LLM_PROVIDER, META_APP_ID, STRIPE_KEY
Where it talks to
mendapi.com (its own)Also cloudflare.com, shopify.dev, nodejs.org, amazon.com, slack.com, github.blog — 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
the tool list (the server exited before answering) · what the tools do when called with real credentials

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names cloudflare.com, shopify.dev, nodejs.org, amazon.com, slack.com, github.blog as well as its own vendor. The guard injects MENDAPI_LLM_API_KEY only into requests to mendapi.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets MENDAPI_LLM_API_KEY=mendapi.com -- npx -y mendapi

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

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-12 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: Access to sensitive file paths; Stripe-like API key pattern detected; Stripe-like API key pattern detected. Summary: no network, touches nothing outside the project, writes no memory.
