## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-19.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint returned HTTP 404.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the Counterparty Due Diligence MCP server?

Counterparty Due Diligence is a hosted endpoint at https://due-diligence-production-1338.up.railway.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (1)

### `counterparty_due_diligence` (~212 tokens)

One-call counterparty screening of a person or company: sanctions (OFAC, EU, UK incl. UN), US export-control lists, PEP (Wikidata), company registry (GLEIF, Norway). Returns no_match, possible_match, confirmed_match or unable_to_determine, confidence, sources and a screening_signal (not a compliance approval). Use when onboarding, contracting with or paying a new counterparty and you want one screening call across sanctions, export-control, PEP and company registries. Paid per call via x402 (USDC on Base).

Input parameters:

- `country` (string): ISO2 country
- `dob` (string): Date of birth (persons)
- `lei` (string): LEI
- `name` (string, required): Person or company name
- `payment_signature` (string): x402 v2 PAYMENT-SIGNATURE header value. Omit to receive payment requirements.
- `registration_number` (string): Registry number
- `type` (string): Default any
