Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

company
company_accounts
Get normalized financials of UK, Danish and Norwegian companies, including private ones, straight from the official accounts they file with Companies House (UK), Erhvervsstyrelsen (Denmark) and the Brønnøysund Register of Company Accounts (Norway): revenue, gross profit, operating profit, net income, equity, net assets, current assets, cash, creditors and employees. Every number comes with the exact fact or field it was taken from, so you can audit any value. Each row also gets the company's LEI from GLEIF when it has one. Look up companies by company number, CVR or organisation number, or get the newest filings. For credit checks, KYB, M&A and lead research, and for AI agents. Price: $0.04 per `company-year`.
company_check
One call answers "who is this company and what are its numbers?": legal name, LEI, registration number, status, legal form, registered address and (France, Finland, Estonia) industry and registration date, the key figures of its last fiscal years (revenue, operating profit, net income, equity, assets, cash, employees), the US listing and latest SEC filings, for UK companies the current directors and owners (persons with significant control), for Polish companies the board, proxies, shareholders and bankruptcy/restructuring entries from the National Court Register (KRS), and for US banks the FDIC record. Every value links to the official record it came from. Built for AI agents doing research, KYB or due diligence, and for people who want a quick, sourced company profile. Price: $0.03 per `company-report`.
counterparty
counterparty_check
Can I do business with this company? One call checks a supplier, customer or partner against official sources and returns a checklist: pass, fail, review or unverified per check, each with its source link and time. Built for AI agents doing KYB, vendor onboarding or "may I pay this party?" checks, and for people who want a fast, sourced first screen. To screen a vendor list, pass up to 10 companies in `companies`: one checklist per company, same price each. Price: $0.05 per `counterparty-check`.
identifier
identifier_resolver
One identifier in, the whole crosswalk out: give an ISIN, LEI, SEC CIK, ticker, FIGI or company name and get the issuer's legal name, LEI, CIK, tickers per exchange, ISINs, FIGIs, CFI code and the EU trading venues, each value with its source URL. Built for AI agents and people who join datasets keyed by different identifiers (KYC, portfolio data, filings research). Price: $0.002 per `resolve`.
plan
plan_official_records_query
Free, no key needed. Turns a question in plain words into the exact typed Bosco Labs calls that answer it: tool, input, why, and the maximum price of each step, plus what is not covered. Pass the user's question verbatim AND the entities you extracted from it (company_names, tickers, identifiers, countries, dates, law references...): the planner trusts your entities over its own parsing and puts them in the right input fields. The plan echoes them in entities_used and lists in `missing` what to pass for a better plan. Rules and examples first; only when they are unsure and you passed no entities does a small AI step extract the entities (budget-capped, marked `assisted`). Same steps, same plan_id. Run it with run_official_records_plan (paid, max_usd) or call the listed tools directly. Low confidence returns the top 3 candidate tools instead.
sanctions
sanctions_screening
Answers "is this company, vessel or person sanctioned?" for one or many names, against the official OFAC SDN and non-SDN lists, the US Consolidated Screening List (Commerce Entity List, Denied Persons, State lists), the UK Sanctions List, the EU financial sanctions list and the UN Security Council list. Every answer says which lists were checked and how current they were, and every match links to its official source. Built for AI agents doing KYB, compliance or procurement checks, and for people who need a quick, sourced screen. It also checks crypto wallet addresses exactly against the addresses OFAC lists (XBT, ETH, USDT, TRX and more), e.g. before an agent pays. Price: $0.01 per `name-screened`.
vat
vat_iban_check
Answers "is this EU VAT number registered, to whom, and is this IBAN real?" One row per VAT number, checked live against the European Commission's VIES service (valid, registered name and address, a name match against the company you expect), and one row per IBAN, checked against ISO 13616 (check digits, length and layout per country, bank code, country match). Built for AI agents doing supplier onboarding, invoice checks and KYB, and for finance teams who want one sourced answer per number. Price: $0.002 per `check`.

KYB due diligence — questions

Answers built from our own checks of this server.

What can KYB due diligence do?
It exposes 7 tools, read directly from the server on our last check. Among them: company_accounts, company_check, counterparty_check, identifier_resolver, plan_official_records_query, sanctions_screening and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is KYB due diligence working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 70 of 70 checks got a reply (100.0%), average response time 521 ms. The bar chart above shows every period we have measured.
How do I connect KYB due diligence?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does KYB due diligence need an API key?
No. KYB due diligence completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is KYB due diligence?
It answers our handshake in 521 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is KYB due diligence open source?
We cannot say either way: written in HTML, 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
