Implementation Reference

• packages/mcp/src/tools/trading.ts:63-82 (handler)

  The 'build_approve_token' tool is defined here. It accepts token details, amount, sender, and optional spender, then calls client.buildApproval and saves the result to a deploy file.

  server.tool(
    'build_approve_token',
    'Build an unsigned token approval transaction. Spender defaults to the CSPR.trade router.',
    {
      token: z.string().describe('Token contract package hash to approve'),
      amount: z.string().describe('Raw amount to approve (in smallest unit / motes)'),
      sender_public_key: z.string().describe('Sender hex public key'),
      spender: z.string().optional().describe('Spender contract package hash (defaults to CSPR.trade router)'),
    },
    async (args) => {
      const bundle = await client.buildApproval({
        tokenContractPackageHash: args.token,
        spenderPackageHash: args.spender ?? '',
        amount: args.amount,
        senderPublicKey: args.sender_public_key,
      });
      const deployPath = await writeDeployFile(bundle.transactionJson);
      return { content: [{ type: 'text' as const, text: bundle.summary + `\n\nUnsigned transaction saved to: ${deployPath}` }] };
    },
  );
