Tools
7 tools: 4 read-only, 3 change data, 0 high risk (delete, pay, send or run code).
- read-only
- Only reads or looks things up. Safe for an agent to call on its own.
- changes data
- Creates, edits or sends something. Worth a person's approval the first time.
- high risk
- Can delete, pay, send on your behalf or run code. Hard or impossible to undo.
Connecting costs an agent about 3,005 tokens of tool definitions and a 1,971 ms handshake.

screen_vesselThe 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: a new self-serve key includes 5,000 liv... - changes data
screen_vesselsBatch-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. - changes data
score_voyageRoute 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 assessm... - read-only
check_vesselScreen 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... - read-only
find_portResolve 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. - read-only
get_screeningFetch a stored screening record by id - the audit copy, retained ten years. Needs ARCNAUTICAL_API_KEY. - read-only
get_usageLive and test usage, remaining allowance, reset time, batch limits and monitor capacity for the configured key.
Levels are automated estimates from each tool's public name, description and annotations, and can be wrong. Descriptions as the server publishes them.

For AI agents
Before connecting, an agent can ask 7Maps for this server's full condition, every tool's risk level and what changed since a person approved it: the road_conditions, watch and route tools on https://7it.co.il/7maps/mcp, paid per call in USDC via x402. About 7Maps.
