korean-tax-mcp@0.18.2
CAUTION· not startedPublisher claims: "Korea (South Korea) tax law MCP server (52 tools) — point-in-time statutes, NTS rulings, court and tribunal decisions, 96 tax treaties and withholding rates, residency and PE tests, transfer pricing; for foreign companies and expats too. 한국 세법 근거 MCP" 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
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, openxmlformats.org, microsoft.com, purl.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, openxmlformats.org, microsoft.com, purl.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.
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; not started: dependency install failed; the server itself was not observed) on 2026-11-15 and scored it 76/100 (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; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
