# Available Tools

> The seven CompliAPI MCP tools and their arguments

Every tool returns the same JSON envelope as its REST counterpart, is metered against your organization's quota, and (without a token) accepts [x402 micropayments](/payments#mcp) per call.

## Screening tools

All five take the value to screen plus an optional `lists` argument — a comma-separated set of [source list](/introduction#source-lists) slugs to narrow the scope (unknown slugs error). Responses match the REST [`/screen/*` envelope](/api/screen): `sanctioned` is true only for government sanctions hits, `flagged` covers crime-intelligence and risk-exposure hits too, and `matches` names the list behind each hit.

| Tool                    | Arguments                 | Screens                                                                                 |
| ----------------------- | ------------------------- | --------------------------------------------------------------------------------------- |
| `screen_crypto_address` | `address`, `lists?`       | A crypto address on any chain; dotted names (e.g. `vitalik.eth`) are ENS-resolved first |
| `screen_email`          | `email`, `lists?`         | An email address                                                                        |
| `screen_website`        | `website`, `lists?`       | A website or domain                                                                     |
| `screen_government_id`  | `government_id`, `lists?` | A government-issued ID (passport, tax ID, …), fuzzy-matched                             |
| `screen_country`        | `country`, `lists?`       | A country or region's sanctions designations (OFAC-curated today)                       |

## Network tools

| Tool           | Arguments    | Returns                                                                                              |
| -------------- | ------------ | ---------------------------------------------------------------------------------------------------- |
| `detect_vpn`   | `ip_address` | Whether the IP is using a VPN — same shape as [`/vpn`](/api/vpn)                                     |
| `geolocate_ip` | `ip_address` | The IP's location, flagging whether it is in a sanctioned country — same shape as [`/geo`](/api/geo) |

## Errors

Over-quota calls return a tool error (or, with [x402 enabled](/payments#mcp), a payment challenge as the error result's structured content). Invalid arguments — an unknown `lists` slug, a malformed IP — also come back as tool errors rather than protocol failures, so agents can read the message and retry.
