`search_participants`

Pack: peppol · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/search_participants for the schema, then POST the same URL with its arguments for the data.

Search the Peppol Directory (directory.peppol.eu, OpenPEPPOL’s opt-in business-card index) by company name, VAT/organisation number or country to find a participant identifier. Use this to turn a company name into the “{schemeCode}:{value}” identifier that lookup_participant needs. Registration on the network does not require publishing a business card, so absence here is not proof a company is not on Peppol — confirm with lookup_participant.

Parameters

Name	Type	Required	Description
`q`	string	yes	Free-text query: company name, VAT number, or organisation number, e.g. “Atelier OSLO” or “1021916675”.
`country`	string	no	Optional 2-letter ISO country code filter, e.g. “NO”, “BE”, “DE”.
`limit`	number	no	Max matches to return, 1-100. Default 10.
