The MCP endpoint gives an agent eight read-only tools. The MCP endpoint is public and needs no login. It supports the 2026-07-28 protocol and a 2025-03-26 compatibility path.
Use the LUCA Pay endpoint for Pay questions:
https://luca-pay-agents-preview.pages.dev/mcp
Use the LUCA Plus endpoint for Plus questions:
https://luca-plus-agents-preview.pages.dev/mcp
For a client that takes a remote MCP URL, add the URL. For a client that needs a local process, use the local MCP guide.
After connection, call get_product_overview.
Then call answer_question with the person's question.
Open the returned source URLs before you answer.
For a modern protocol check, send server/discover:
curl -X POST 'https://luca-pay-agents-preview.pages.dev/mcp' \
-H 'Content-Type: application/json' \
-H 'Accept: application/json, text/event-stream' \
-H 'MCP-Protocol-Version: 2026-07-28' \
-H 'Mcp-Method: server/discover' \
-d '{"jsonrpc":"2.0","id":1,"method":"server/discover","params":{"_meta":{"io.modelcontextprotocol/protocolVersion":"2026-07-28","io.modelcontextprotocol/clientInfo":{"name":"example","version":"1.0"},"io.modelcontextprotocol/clientCapabilities":{}}}}'
The endpoint is read-only. It does not collect leads or submit an application.
