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
MD_APP_SECRETMD_HAP_PATMD_V1_TOKEN_MODEMD_V1_TOKEN_REMOTE_PATHMD_V1_TOKEN_SSH_HOSTMD_V1_TOKEN_SSH_KEYMD_V1_TOKEN_SSH_USERConfiguration, not credentials: MD_ACCOUNT_ID, MD_APP_KEY, MD_CALLBACK_PORT, MD_HOOK_URL, MD_KEY, MDYMCP_INSTALL_DEBUG, MDYMCP_SKIP_PAT_PROMPT
Where it talks to
no vendor host named in the codeAlso mingdao.com, githubusercontent.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 mingdao.com, githubusercontent.com as well as its own vendor. The guard injects MD_APP_SECRET, MD_HAP_PAT, MD_V1_TOKEN_MODE, MD_V1_TOKEN_REMOTE_PATH, MD_V1_TOKEN_SSH_HOST, MD_V1_TOKEN_SSH_KEY, MD_V1_TOKEN_SSH_USER only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx mdymcp

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 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; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
