Cited company background reports for agents from official registries. $3 per report via x402.
Dutiful is a remote MCP server that lets an assistant look up companies in official registries and buy cited background reports for $3 in USDC.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/work.dutiful%2Fdutiful/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Research you can cite. Before paying a registered supplier, check that the legal entity matches the business you mean. A Dutiful Company Report brings official registry facts, a company-level, name-only screen of the OFAC SDN and UK Sanctions List, and a news and web scan into one cited report. It is background research, not a verdict that a company is safe to trade with.
Check coverage free before buying a report. Registry fields vary by country; US coverage is limited to SEC-reporting entities and Canada to federal corporations. EU and UN lists are not screened. No match is not clearance.
The full Company Report costs $3.00 USDC on Base via x402. Payment requires a separate wallet-signing step; create_order returns payment requirements and does not pay.

Tools:
check_coverage - check whether a company is in a covered registry (free)create_order - create a report order and get x402 payment requirementsget_report - fetch the finished reportServer card: https://dutiful.work/.well-known/mcp/server-card.json
Requires Node.js 22 and npm. Run once in a new folder:
This calls only check_coverage, not create_order or a payment endpoint. No account, API key, wallet or signature is needed. The free check creates or reuses a pending order/cache record internally; it is zero-payment, not stateless. Rate limits apply, so do not run it repeatedly to poll.
A separate smoke test with SDK 1.32.2 / Node 22.23.4 on 2026-10-29 observed initialization negotiating protocol 2025-06-18, tools/list returning the three tools, and this GB lookup returning five candidates. The SDK's optional background SSE GET returned 405, but the POST-based check completed. This shortened quickstart was syntax-checked and replayed offline, not rerun against the remote service. This is evidence for this client and free flow, not every client or the paid flow.
Example output, abbreviated to public fields (matches can change):
No candidate is selected and no report is purchased. Keep pending order IDs and session headers out of public logs. If the check fails or finds no suitable match, stop; do not proceed to a paid call.
Question: "Does this name point to the company I mean, and what would a report leave out?"
For a UK company, compare the legal name and company number, not just the trading name. The free Sainsbury's sample identifies J SAINSBURY PLC as company 00185647 and links to its Companies House record. The sample is a dated example, not a current check of that company.
Before paying for your own company check, run check_coverage with the company name and country (for example, {"company":"J SAINSBURY PLC","country":"GB"}). Review the returned matching entities and country-specific report scope. The check is free and does not buy a report. Do not assume which match index will be returned.
The sample's gaps matter: it does not cover credit scores/payment behaviour, PEP screening or civil litigation, and it does not identify beneficial owners beyond what the register publishes. A registry match is not a verdict that a company is safe to trade with. US coverage is limited to SEC-reporting entities and Canada to federal corporations; the company-level sanctions screen covers the OFAC SDN and UK Sanctions List; EU and UN lists are not screened.
If you choose to continue, create_order returns payment requirements, not payment. Company Reports cost $3.00 USDC on Base via x402, with a separate wallet-signing/payment step. Connection and payment quickstart.

12 registries. US coverage is SEC-reporting companies; Canada is federal corporations. The screen covers the OFAC SDN and UK Sanctions List plus a news and web scan; EU and UN lists are not screened. A report is not a credit check or a legal opinion.

Check coverage
Free. Searches the official company register of the given country for the company name and returns the matching entities (idx, registry reference, name, address), an order id, and what a report covers. Nothing is charged. Supported country codes: GB, FR, NO, FI, CZ, EE, SK, LV, IL, CA, CY, US (CA: federal corporations only; US: SEC reporting companies only).
companyrequiredcountryrequiredCreate order
Selects one entity from the check_coverage results (idx, starting at 0) and returns the x402 payment requirements for a report (USDC on Base, exact amount in the requirements). This tool does not pay. To pay, send the signed payment in a PAYMENT-SIGNATURE header to the returned pay_url, then read the report with get_report.
idxrequiredcompanyrequiredcountryrequiredGet report
Returns the status of an order and, once delivered, the report (structured JSON and plain text). Status values: pending_entity, pending_payment, paid, delivered. An unpaid order returns its payment requirements.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
