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
UPSTAGE_API_KEYConfiguration, not credentials: KOREAN_TAX_MCP_CACHE, KOREAN_TAX_MCP_CACHE_TTL, KOREAN_TAX_MCP_DOCS, KOREAN_TAX_MCP_MODEL, KOREAN_TAX_MCP_SOLAR_BASE_URL, KOREAN_TAX_MCP_SOLAR_KEY, KOREAN_TAX_MCP_SOLAR_VERIFY, KTM_CACHE_TTL, KTM_LAW_ARTICLE_BUDGET, KTM_RESP_MAX_CHARS, LAW_OC
Where it talks to
no vendor host named in the codeAlso go.kr, doi.org, upstage.ai — 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 go.kr, doi.org, upstage.ai as well as its own vendor. The guard injects UPSTAGE_API_KEY only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx korean-tax-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 2026-11-14 and scored it 94/100 (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.
