Lithuanian Public Procurement MCP

MCP server for working with Lithuanian public procurement data.

Main source – the public API of the new CVP IS: https://viesiejipirkimai.lt/epps-integration/api/cft-details-export

The server is intended for ChatGPT / Claude / another MCP client:

• fetch procurement pages from the new CVP IS via the official VPT API;

• search the retrieved procurements by text;

• filter by procurement number, organization, supplier, or other text;

• return raw JSON data for further analysis;

• provide links to the old and new CVP IS search.
