Implementation Reference
- The handler function for the "mint_loyalty_tokens" MCP tool, which validates the request, checks the loyalty program in the database, records the mint intent, and generates contract calldata.
handler: async ({ token_address, recipient, amount }: any) => { const err = authGuard(["mint"]); if (err) return T(err); if (!/^0x[a-fA-F0-9]{40}$/.test(recipient)) return T('{"error":"Invalid recipient address"}'); const d = db(); const { data: prog } = await d.from("loyalty_programs").select("id,name,symbol,status").eq("token_address", token_address.toLowerCase()).eq("merchant_address", agent.ownerAddress).single(); if (!prog) return T('{"error":"Program not found"}'); if (prog.status !== "active") return T(JSON.stringify({ error: `Program is ${prog.status}` })); const { data: mint, error } = await d.from("token_mint_history").insert({ merchant_address: agent.ownerAddress.toLowerCase(), recipient_address: recipient.toLowerCase(), amount, token_address: token_address.toLowerCase(), token_name: prog.name, token_symbol: prog.symbol }).select("id,amount,recipient_address,token_address,created_at").single(); if (error) return T(JSON.stringify({ error: error.message })); return T(JSON.stringify({ mint, contract_call: { to: token_address, function: "mint(address,uint256)", args: [recipient, amount], calldata: encodeMintCalldata(recipient, amount), chain: "Base (8453)", builder_code: BUILDER_CODE } })); }, - supabase/functions/loyalty-mcp/index.ts:144-159 (registration)Registration of the "mint_loyalty_tokens" tool within the MCP server setup.
