api record

ArcNautical screens commercial vessels for sanctions and risk. Identify a ship by its seven-digit IMO number (never by name alone: names repeat and change). Use check_vessel for a quick verdict with no key; use screen_vessel for the full evidence record when an API key is configured. Sanctions status semantics: RED = confirmed match on the vessel identifier, AMBER = possible match needing review, GREEN = no match against the sources reached, INCOMPLETE = a core source could not be read, which must never be presented as clear. Always quote the status, the checkedAt/screened_at time, and say…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 7 tools
7 never probed 0 of 7 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_usage unknown never probed

    Live and test usage, remaining allowance, reset time, batch limits and monitor capacity for the configured key.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • check_vessel unknown never probed

    Screen one vessel by IMO number against OFAC SDN, EU, UN, UK OFSI and OpenSanctions, with an ownership-opacity score and an A–E vetting grade from port-state-control history. Works with no API key. Rate-limited to 100 requests per hour per IP. Returns the VERDICT SUMMARY only; for every sanctions match with its source list and confidence class use screen_vessel (needs a key).

    mcp-tool

    {

      "description": "Seven-digit IMO number of the vessel"
    }
  },
  "additionalProperties": false
}
    arguments 15 lines
  • find_port unknown never probed

    Resolve a port name, country or partial UN/LOCODE to the LOCODEs the routing engine knows. Routes are addressed by LOCODE, so call this before score_voyage rather than guessing a code. Works with no API key.

    mcp-tool

  • screen_vessel unknown never probed

    The authenticated screening record for one vessel: every sanctions match with its source list, programme and confidence class, ownership opacity, the graded vetting factors, per-source freshness, and a retained record id. Needs ARCNAUTICAL_API_KEY. Metered: 5,000 live screenings a month are included with a self-serve key. The same vessel asked again on the same day replays the stored record free. If the result is INCOMPLETE for identity, call again with vessel_name.

    }
  },
  "additionalProperties": false
}
    arguments 30 lines
  • screen_vessels unknown never probed

    Batch-screen a list of IMO numbers and wait for the results (up to two minutes). Returns one verdict per hull plus the batch status. Needs ARCNAUTICAL_API_KEY. Each hull spends one screening unit unless it was already screened today.

    arguments 15 lines
  • score_voyage unknown never probed

    Route risk between two ports (UN/LOCODEs): a 0–100 score, risk level, the signals driving it (war-risk areas, piracy, chokepoints, weather, sanctions exposure of transited EEZs), confidence and any missing sources. Resolve port names with find_port first. Needs ARCNAUTICAL_API_KEY; 10,000 assessments a month are included with a self-serve key.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
