clevertech-mcp-server@0.4.2

CAUTION· startup only

Publisher claims: "CleverTech MCP server — Canadian government data for AI agents: property, permits, zoning, business registry, and GPS ↔ DLS conversion. Free tier available." 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
CLEVERTECH_API_KEYRAILWAY_API_TOKENRAILWAY_TOKENSENTRY_DSNConfiguration, not credentials: CLEVERTECH_API_URL, RAIL, RATE_LIMIT_ANON_BURST, RATE_LIMIT_ANON_DAILY, TRANSPORT
Where it talks to
clevertech.ca (its own)Also python.org, astral.sh, railway.app — 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 python.org, astral.sh, railway.app as well as its own vendor. The guard injects CLEVERTECH_API_KEY, RAILWAY_API_TOKEN, RAILWAY_TOKEN, SENTRY_DSN only into requests to clevertech.ca (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.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-14 and scored it 77/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
