Implementation Reference
- The handler function that executes the transfer_loyalty_tokens logic, including authentication, input validation, program verification, and calldata generation.
handler: async ({ token_address, to, amount }: any) => { const err = authGuard(["mint"]); if (err) return T(err); if (!/^0x[a-fA-F0-9]{40}$/.test(to)) return T('{"error":"Invalid recipient address"}'); const d = db(); const { data: prog } = await d.from("loyalty_programs").select("id,name,status").eq("token_address", token_address.toLowerCase()).eq("merchant_address", agent.ownerAddress).single(); if (!prog) return T('{"error":"Program not found or not owned by you"}'); if (prog.status !== "active") return T(JSON.stringify({ error: `Program is ${prog.status}` })); return T(JSON.stringify({ contract_call: { to: token_address, function: "transfer(address,uint256)", args: [to, amount], calldata: encodeTransferCalldata(to, amount), chain: "Base (8453)", builder_code: BUILDER_CODE } })); }, - supabase/functions/loyalty-mcp/index.ts:161-174 (registration)The registration of the transfer_loyalty_tokens tool with its description and input schema.
