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.

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 sec.gov, bis.org, treasury.gov, yahoo.com, oecd.org, europa.eu, bankofengland.co.uk, imf.org, stlouisfed.org, bankofcanada.ca, go.jp, cboe.com, arcgis.com, wikimedia.org, fdic.gov, bls.gov, bea.gov, census.gov, federalreserve.gov, cirrun.com, house.gov, usda.gov, llama.fi, deribit.com, eia.gov, xbrl.org, dartmouth.edu, okx.com, ssga.com as well as its own vendor. The guard injects ALPACA_API_KEY_ID, ALPACA_API_SECRET_KEY, ALPACA_PAPER_SECRET_KEY, APCA_API_KEY_ID, APCA_API_SECRET_KEY, TIINGO_API_KEY only into requests to canlicapital.com (and its subdomains) and refuses the rest.
