mcp-cms-open-payments

CMS Open Payments, with annual dataset discovery through the official DKAN API.

Part of Pipeworx — an MCP gateway connecting AI agents to 1361+ live data sources.

Tools

Tool	Description
open_payments_search	Search one CMS Open Payments program-year dataset using structured recipient, company, product, geography, payment-nature, and amount filters. CMS publishes company-reported relationships; a payment does not imply wrongdoing or a conflict.
open_payments_physician	Find CMS Open Payments records for a physician/non-physician practitioner by exact NPI in one program year. Returns the authoritative total match count plus a bounded payment sample; reported relationships do not imply misconduct. If you have a name rather than an NPI, resolve it first against the NPPES registry (npi_individual in the clinicaltables pack), or use open_payments_search with recipient_last_name + recipient_first_name.
open_payments_company	Search payments reported by a manufacturer or GPO in one CMS Open Payments program year. Company matching is a case-insensitive substring and may combine similarly named legal entities.
open_payments_product	Search general-payment records associated with a named drug, biologic, device, or medical supply across all five CMS product slots. Product association is reporting-entity supplied and does not prove the payment was exclusively for that product.
open_payments_research	Search CMS research-payment records by company, recipient NPI, study name, or state for one program year. Amounts may represent funding routed through an institution and should not automatically be attributed as personal compensation.
