What this server can do
5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
diligence(wallet, company)- Combined counterparty due diligence in one call: runs sanctions screening on a crypto wallet (Chainalysis oracle — OFAC SDN, EU, UN) AND a UK Companies House KYB lookup (status, type, PSC / beneficial owners) in parallel. Built for compliance agents vetting a counterparty that has both an on-chain wallet and a UK company. Returns both independent results, plus an explicit disclaimer that no verified link between the wallet and the company is established by the data. Required: wallet, company.
screen_name(name, threshold)- OFAC name screening: fuzzy-match a person or company name against the official US Treasury OFAC Specially Designated Nationals (SDN) list (primary names + strong aliases). Returns scored candidate matches with the matched name, SDN type, and program. SCOPE: this is a screening aid for AML / KYC / sanctions compliance — a match is a candidate to investigate with secondary identifiers (DOB, nationality, ID), NOT a determination. Weak AKAs are not screened, per OFAC guidance. Required: name.
screen_wallet(address)- Sanctions screening for a crypto wallet address. Checks an EVM address against the Chainalysis on-chain sanctions oracle, which covers OFAC SDN, EU, and UN designated addresses (including Tornado Cash and other sanctioned protocols). Returns a clear sanctioned / not-sanctioned result with the matching program. Use for AML compliance, counterparty due diligence, and payment screening before sending USDC or any funds to an address. Required: address.
verify_uk_company(companyNumber)- UK company verification and KYB (know-your-business) lookup via the official Companies House register. Given a UK company registration number, returns legal status (active / dissolved), company type, incorporation date, registered office address, and the people with significant control (PSC / beneficial owners). Use for KYB onboarding, supplier and counterparty due diligence, and confirming a UK business is real, active, and who controls it. Authoritative UK government open data. Required: companyNumber.
verify_us_company(query)- US public company verification via the SEC EDGAR system. Given a ticker, SEC CIK, or company name, returns the registered entity name, CIK, industry (SIC code), state of incorporation, listed exchanges and tickers, business address, and most recent SEC filing. SCOPE: EDGAR covers SEC-registered PUBLIC companies and funds only — NOT private US companies, which register at the state level. Use for KYB and counterparty due diligence on listed US entities. Authoritative US government open data. Required: query.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| GitHub stars | 0 | Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. | cumulative, all time | GitHub | |
| Last commit | 2026-07-08 | Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. | point in time | GitHub | |
| Open issues | 0 | Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. | as of fetch | GitHub | |
| Latest published version | 1.1.0 | Latest version string the maintainer published to the registry. | as of fetch | Model Context Protocol | |
| Registry record last updated | 2026-06-27 | When the registry record was last updated by its maintainer. | point in time | Model Context Protocol | |
| First listed in the MCP Registry | 2026-06-27 | Date this server was first published to the official MCP Registry. Not a usage or quality measure. | point in time | Model Context Protocol | |
| repository status | active | The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on. | as of fetch | GitHub | |
| mcp tools declared | 5 tools | Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work. | as of probe | mcp.onchaindiligence.com | |
| mcp endpoint status | ok | The server listed 5 functions when asked. | as of probe | mcp.onchaindiligence.com |

These share tags the maintainers applied themselves, such as sanctions, x402, sdk. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.
This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
