Server instructions

Stateless MCP endpoint at POST /mcp. Protocol 2026-07-28 uses MCP-Protocol-Version, Mcp-Method, and Mcp-Name headers. Legacy initialize also works for 2025-11-25, 2025-06-18, and 2025-03-26. No session. No authentication. Tools: get_rule, search_rules, explain_error, and check_invoice. The first three return the stored statement, the plain reading, the fix, and the source URL. check_invoice reads a UBL slice and returns the terms it writes, the field-map gaps, and one stored BR-DE-15 note when buyer reference BT-10 is absent. evaluation stays false. The body is not stored. The same reading is POST /v1/invoices/check. There is no UBL write route.
