```untrusted-server-text
The server marks "match_native_usdc_payment" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "match_native_usdc_payment" says "payment": a word that usually means money moves, which cannot be taken back.
